stability order of alkenes 里面讲越多substitute, 分子越稳定。
讲原因的时候,提到MO 理论,hyperconjugation grouping,every C=C has an empty
p antibonding orbital, 我一直理解为 C=C bond can only have eiher bonding p
or nonbonding p orbital. because when they have the same sign, they form
bonding p; opisite sign, nonbonding p.
难道是c=c 加一起bonding and nonbonding 各一个么?
书上讲的很少,也不影响做题考试,就是很好奇想知道。
