올려 달라고 하셨는데 무시하기가 그래서
아주 짧게 짧게 올려봅니다. ㅎㅎㅎ

ADDITION REACTIONS
The bond enthalpy of the C=C double bond in alkenes has a value of 61 2 kJ mol- 1. This is less than twice the average value of
348kJ mol- 1 for the CC single bond and accounts for the relative reactivity of alkenes compared to alkanes. The most important
reactions of alkenes are addition reactions. Reactive molecules are able to add across the double bond. The double bond is said to be
unsaturated and the product, in which each carbon atom is bonded by four single bonds, is said to be saturated
일요일 수업을 5개 하고! 5시간이 아닙니다. ㅎㅎ
그 느낌 살려서 조금 찍어서 올려 봅니다.
다음에 또 올리도록 하겠습니다.
영상을 헨폰으로 찍었는데 소리가 너무 작습니다. 필요하신분들은 이어폰을 끼고 들어보세요!
IB 도 그렇고 AP 도 그렇고 Organic chemistry 중요한데요. 제가 중요한 부분만 딱딱 조금씩 설명해서 올리도록 하겠습니다.
