Vedclass · Answer

(B) The correct answer is $(B)$.According to $IUPAC$ nomenclature rules,when three or more identical carbon-containing functional groups (like $-CN$) are attached to the same parent chain,the carbon atoms of these functional groups are excluded from the main chain.In the compound $NC-CH_2-CH(CN)-CH_2-CN$,the main chain consists of $3$ carbon atoms (propane).The suffix used for the $-CN$ group in this specific situation is 'carbonitrile'.Therefore,the correct name is Propane$-1,2,3-$tricarbonitrile.
