Of the following compounds, the oxime of which shows geometrical isomerism, is

A)  acetone

B)  diethylketone

C)  formaldehyde

D)  benzaldehyde

Correct Answer: D

Solution :

\[{{C}_{6}}{{H}_{5}}-\overset{\begin{smallmatrix}  O \\  || \end{smallmatrix}}{\mathop{C}}\,-H+N{{H}_{2}}OH\xrightarrow{{}}\]\[\underset{benzaldehyde\text{ }oxime}{\mathop{{{C}_{6}}{{H}_{5}}CH=NOH}}\,\] It shows geometrical isomerism. Syn anti
