Geometrical isomerism is not possible in

Answer»

2,4-hexadiene
benzaldoxime
but-2-ene
benzophenone oxime

Solution :`CH_3overset2CH=overset3CH-overset4CH=overset5CHoverset6CH_3` shows geometrical isomerism AROUND `C_3-C_4` single bond.
shows geometrical isomerism around C=N bond.
`CH_3CH = CHCH_3` and ClCH=CHCl SHOW geometrical isomerism around C =C bond
Benzophenone oxime having TWO identical GROUPS on the doubly bonded carbon does not show geometrical isomerism.
