Vedclass · Answer

(D) The given molecule is $4$-methylcyclohexylidene-but$-2-$enoic acid.It contains two stereogenic centers/elements that can exhibit geometrical isomerism:$1$. The exocyclic double bond on the cyclohexane ring: Since the ring is substituted at the $4$-position with a methyl group,the exocyclic double bond can exhibit geometrical isomerism ($E/Z$ or $cis/trans$ relative to the ring substituents).$2$. The double bond in the side chain $(-CH=CH-)$: This double bond can also exhibit geometrical isomerism ($E/Z$ or $cis/trans$).Since both stereogenic elements are independent and can each exist in two configurations,the total number of stereoisomers is $2^n$,where $n=2$.Total stereoisomers = $2^2 = 4$.
