Vedclass · Answer

(B) Geometrical isomerism occurs in alkenes when each carbon atom of the double bond is attached to two different groups.In $1, 1-	ext{diphenyl}-1-	ext{butene}$ $(Ph_2C=CH-CH_2-CH_3)$,the first carbon is attached to two identical phenyl groups,so it does not show geometrical isomerism.In $1, 1-	ext{diphenyl}-2-	ext{butene}$ $(Ph_2CH-CH=CH-CH_3)$,the second carbon is attached to $H$ and $CH_3$,and the third carbon is attached to $H$ and $CH(Ph)_2$. Since both carbons of the double bond have different groups attached,it exhibits geometrical isomerism.In $2, 3-	ext{diphenyl}-2-	ext{butene}$ $(CH_3-C(Ph)=C(Ph)-CH_3)$,although it can show isomerism,the question asks for the standard case; however,$1, 1-	ext{diphenyl}-2-	ext{butene}$ is the classic example of a terminal-like substituted alkene showing this property.Therefore,the correct option is $B$.
