"The benzene ring is the structure of the benzene molecule. It is a planar regular hexagon, each vertex is a carbon atom, and each carbon atom is combined with a hydrogen atom. The carbon-carbon bond in the benzene ring is between a single bond and a double bond The unique bond, the bond angle is 120°, and the bond length is 1.40°."

After lunch, in the library, Luo Hao looked at the serious fat man, and felt a little relieved in his heart: "Fortunately, I'm listening carefully, otherwise I would have cursed."

After a pause, Luo Hao continued: "The molecular formula of benzene is c6h6. Although benzene should show a high degree of unsaturation from the perspective of carbon-to-hydrogen ratio, benzene does not have the properties of unsaturated hydrocarbons. Generally, benzene It is not easy to undergo electrophilic addition reactions such as olefins, nor is it oxidized by potassium permanganate, and it is prone to substitution reactions of benzene rings, such as halogenation, nitration, sulfonation, alkylation and acylation, etc. These reactions are maintained The original structure of the benzene ring. These properties fully demonstrate that benzene has properties different from saturated compounds, and it is not easy to add, not easy to oxidize, easy to replace, and the carbon ring is abnormally stable. These properties are collectively called aromaticity. The aromaticity of benzene and the benzene ring are closely related to the special structure of

Luo Hao patiently explained, but the fat man's expression gradually changed.

"Brother Hao, I can understand what you said earlier, but what did you say later?" The fat man scratched his hair in a daze.

Luo Hao shook his head: It seems that there is a long way to go to tutor Fatty.

"Let's go back first, it's almost time for the afternoon class." Luo Hao called the fat man.

"Is it necessary to learn this level of the benzene ring we taught in high school?" On the way back to the classroom, the fat man still felt unbelievable.

"If you want to get a high score, you have to learn this level. If you just want to pass the exam, just remember what Luo Hao said earlier." Huang Xi said before Luo Hao could speak.

"Huh?" Fatty's face was filled with lovelessness.

Talking and laughing all the way, several people returned to the classroom.

"Students, after the meeting in the morning, the time for the one-model exam has been confirmed." Han Xue stood on the podium, "From the perspective of the status of the exam, the one-model exam has the function of 'connecting the past and ushering in the future'. Everyone has entered the third grade of high school. It has been more than a semester, and this one-model exam is a summary of everyone's efforts over the past six months. At the same time, everyone can pass this exam and see their own weaknesses. We still have two months to go. It is time to make up for these weaknesses. In addition, this exam will carry out a city-wide ranking, which will also allow everyone to see what level they belong to in the city, and their eyes should not be limited to this school."

Luo Hao listened to Han Xue on the podium doing pre-examination mobilization, and the system's task prompt sounded in his mind:

Ding--

System task release...

Hearing the system's notification sound, Luo Hao was uncharacteristically not particularly happy to check the tasks, but remained silent.

Time flies, in a blink of an eye, it has been more than a month since I got the system, and in just one month, earth-shaking changes have taken place in myself.An unknown student who was worried every day about not being able to get into the same university as his girlfriend, suddenly became a top student in the school.

Everything was so incredible that Luo Hao felt like he was living in a dream this month.He was afraid that he would wake up from his dream and find that he was still that obscure student.

Luo Hao raised his head. Since he was worried that external assistance would eventually be lost, he should try to become a better version of himself. Only the knowledge, strength, and everything else that he could master could give him enough sense of security, so that he would no longer be frightened. , to be able to make myself do whatever I want.

At this moment, Luo Hao's mind seemed to have light, his mind was peaceful, and all his troubles were gone.

At this time, Luo Hao didn't notice, and the system prompt appeared again quietly:

The system detects that the host has obtained spiritual sublimation and has passed the hidden test of the system. The system will fully bind and fuse with the host within the next 12 hours.The existing functions of the system will not affect the use. After the binding and integration, the system will gradually release other functions.

Ding--

System hidden test achievement reward: the host gets 5 charm points.

Ding--

Binding fusion begins.

Countdown: 11:59:59

"Huh? What was the prompt just now?" Luo Hao came back to his senses, "Forget it, open the property panel and have a look."

Host: Luo Hao

Age: 17 years old

Educational level: slightly accomplished

Skills: photographic memory, mastery, ten lines at a glance, master calligraphy proficiency

Constitution: 7

Agility: 6

Spirit: 8

Charisma: 5

"Charm value? What is it? When did it come out?" Luo Hao asked the system three times in a daze.

"The charm value can increase the charm of the host. The higher the charm value, the host's appearance will undergo slight changes and gradually reach perfection. The charm value can also increase the favorability of others towards the host. The host's spiritual sublimation has just completed the hidden test of the system. Charm points are hidden test rewards." The system replied.

For some reason, Luo Hao felt that the system was a little different from usual, but he didn't care.

"Friendly reminder: The host still has system tasks that have not been checked." The system said suddenly.

"Almost forgot, there is a new task. Open the task list."

Task: a mock exam

Mission goal: to achieve No.1 in the city in the one-mode test.

Task reward: 10 kiwi fruits.

"Kiwi fruit? Kiwi fruit? Just give 10 kiwi fruits for such a difficult task?" Luo Hao had [-] alpacas rushing past him, "Dog system! What does this mean?"

"Warning, you will be punished for insulting the system again. In addition, the products produced by the system must be high-quality goods."

"..." Luo Hao didn't dare to scold him now.

"Brother Hao? Luo Hao? Rat?"

"Huh? What's the matter?" Luo Hao came back to his senses and turned to look at the fat man.

"What are you thinking? I called you for a long time and you ignored me, and you laughed strangely and gritted your teeth." The fat man looked curious.

"Oh? Yes? No? By the way, what did you call me for?" Luo Hao laughed.

"Oh, I'm just asking how to do this question." The fat man gave Luo Hao the test question.

"Okay, I'll take a look."

……

"Student Luo Hao, can you help me with this question later?"

"it is good."

Luo Hao spent the whole afternoon between brushing the questions and being asked for advice.Looking at the progress value of the achievement of helping others in the achievement task, Luo Hao felt happy from the bottom of his heart. Of course, Luo Hao also experienced the joy of helping others.

After school, Luo Hao walked to Class [-] of the third year as usual.

"Xiao Xi, let's go." Luo Hao stood at the door of the classroom and looked at Huang Xi.

"What are you always staring at me? I know I'm handsome, but I haven't been handsome for a day or two."

In the corridor, Luo Hao asked curiously.

"It's really narcissistic, but why do I feel that you are different today? It seems that you are more handsome?" Huang Xi hesitated, as if he didn't know how to describe it.

"Xiao Xi, do you like me?" Luo Hao suddenly moved his face towards Huang Xi and asked.

Huang Xi's face turned red all of a sudden: "Not serious. Hurry up, the teacher should be waiting."
