$R_2C=CR_2$

Vedclass · Answer

(D) The stability of alkenes is determined by the number of alkyl groups attached to the doubly bonded carbon atoms due to the hyperconjugation effect and inductive effect.Greater the number of alkyl groups attached to the $C=C$ bond,greater is the stability of the alkene.The order of stability is: $R_2C=CR_2 > R_2C=CHR > RCH=CHR > R_2C=CH_2 > RCH=CH_2 > CH_2=CH_2$.Therefore,the alkene with the maximum number of alkyl groups,$R_2C=CR_2$,is the most stable.

Which among the following alkenes is most stable?
