Vedclass · Answer

(A) The given compound is $CH_3-CO-CH_2-C(CH_3)_2-CN$. According to $IUPAC$ priority rules,the nitrile group $(-CN)$ has higher priority than the ketone group $(>C=O)$. Therefore,the carbon of the $-CN$ group is assigned number $1$. The numbering of the chain is: $C(5)H_3-C(4)(=O)-C(3)H_2-C(2)(CH_3)_2-C(1)N$. Substituents: Two methyl groups at $C2$ ($2,2-$ dimethyl) and an oxo group at $C4$ ($4-$ oxo). Parent chain: Pentanenitrile. Thus,the $IUPAC$ name is $2,2-$ Dimethyl $-4-$ oxopentanenitrile.
