Vedclass · Answer

(D) Grignard reagents $(RMgX)$ are strong bases and react rapidly with compounds containing acidic hydrogen atoms (such as $-OH$,$-SH$,and $-NH_2$ groups).In options $(a)$,$(b)$,and $(c)$,the molecules contain acidic hydrogen atoms attached to oxygen,sulfur,or nitrogen,which would immediately protonate the Grignard reagent.In option $(d)$,the nitrogen atom is part of a tertiary amine group $(-N(CH_3)_2)$,which does not have an acidic hydrogen.Therefore,this Grignard reagent can be prepared.

Which of the following Grignard reagents can be prepared?
