$3-$ethylhex$-3-$ene

Vedclass · Answer

(D) Stereoisomerism includes both geometrical and optical isomerism.$A$. $3,4-$dimethylhex$-3-$ene: The $C=C$ bond has two ethyl groups on one carbon and two methyl groups on the other. Wait,let's re-evaluate: $CH_3CH_2-C(CH_3)=C(CH_3)-CH_2CH_3$. This shows geometrical isomerism $(cis/trans)$.$B$. $4-$methylhex$-1-$ene: $CH_2=CH-CH_2-CH(CH_3)-CH_2CH_3$. It has a chiral center at $C-4$,so it shows optical isomerism.$C$. $3-$methylhex$-1-$ene: $CH_2=CH-CH(CH_3)-CH_2CH_2CH_3$. It has a chiral center at $C-3$,so it shows optical isomerism.$D$. $3-$ethylhex$-3-$ene: $CH_3CH_2-C(CH_2CH_3)=CH-CH_2CH_3$. The $C=C$ bond has two identical ethyl groups attached to the $C-3$ atom. Therefore,it does not show geometrical isomerism. Also,there is no chiral center,so it does not show optical isomerism. Thus,it does not show stereoisomerism.

Which one of the following molecules does not show stereoisomerism?
