Vedclass · Answer

(B) The smallest ketone is acetone $(CH_3COCH_3)$. Its reaction with $NH_2OH$ gives acetone oxime,which is $(CH_3)_2C=NOH$. This molecule has identical groups on the carbon atom,so it does not show geometrical isomerism.The next homologue is butan$-2-$one $(CH_3COCH_2CH_3)$. Its reaction with $NH_2OH$ gives butan$-2-$one oxime,which is $CH_3(C_2H_5)C=NOH$. This molecule has different groups on the carbon atom,so it exhibits geometrical isomerism,resulting in two geometrical isomers ($syn$ and $anti$ forms).Thus,in total,there are $1 + 2 = 3$ different oximes formed.

$A$. Grignard reagent	$1$. $H_2 / Pd-BaSO_4$
$B$. Clemmensen reduction	$2$. $N_2H_4 / KOH / (CH_2OH)_2$

The smallest ketone and its next homologue are reacted with $NH_2OH$ to form oximes.
