Vedclass · Answer

(C) $1$. Identify the principal functional group. The nitrile group $(-CN)$ has higher priority than the ketone group $(=O)$. Thus,the parent chain is a nitrile.$2$. Number the chain starting from the carbon of the $-CN$ group as $C-1$.$3$. The chain is $CH_3-C(CH_3)_2-CH_2-C(=O)-CH_3$. Numbering gives: $C-1$ (nitrile carbon),$C-2$ (quaternary carbon with two methyl groups),$C-3$ (methylene group),$C-4$ (ketone carbonyl),$C-5$ (terminal methyl).$4$. The substituents are two methyl groups at $C-2$ and an oxo group at $C-4$.$5$. Combining these,the $IUPAC$ name is $2,2-$dimethyl$-4-$oxopentanenitrile.

The $IUPAC$ name of the compound $X$ is:
