Vedclass · Answer

(B) The reactant is $1,2,3,4$-tetrahydroquinazoline. It contains two nitrogen atoms: one is an aniline-type nitrogen (attached to the benzene ring) and the other is an aliphatic amine-type nitrogen. The aliphatic amine nitrogen is more basic than the aniline-type nitrogen because the lone pair on the aniline nitrogen is delocalized into the benzene ring. Therefore,when $1 	ext{ mole}$ of $HCl$ is added,the more basic aliphatic nitrogen atom gets protonated to form the corresponding ammonium salt. The correct product is the one where the aliphatic nitrogen is protonated,which corresponds to option $B$.
