Vedclass · Answer

(B) The priority order of functional groups is $-CN > -CHO > >C=O$. Therefore,the principal functional group is nitrile $(-CN)$. The longest carbon chain containing the $-CN$ group is selected as the parent chain,and numbering starts from the carbon of the $-CN$ group. The $-CHO$ group at position $2$ is treated as a substituent and named 'formyl',and the keto group at position $3$ is named 'oxo'. The parent chain has $5$ carbons,so it is 'pentanenitrile'. The correct $IUPAC$ name is $2-$formyl$-3-$oxopentanenitrile.

The correct $IUPAC$ name of the compound $CH_3-CH_2-C(=O)-CH(CN)-CHO$ is:
