Vedclass · Accepted Answer

$NH_4^+$

Vedclass · Answer

(A) The acidic strength of an acid is inversely proportional to the basic strength of its conjugate base. $1$. The conjugate base of $NH_4^+$ is $NH_3$. $2$. The conjugate base of the ion in option $B$ is $1,2,3,4$-tetrahydroisoquinoline. $3$. The conjugate base of the ion in option $C$ is $1,2,3,4$-tetrahydroquinoline. $4$. The conjugate base of the ion in option $D$ is piperidine. Among these,$NH_3$ is the least basic because it lacks the electron-donating alkyl groups present in the other cyclic amines. Since $NH_3$ is the weakest base,its conjugate acid $NH_4^+$ is the strongest acid.
