Vedclass · Answer

(D) In the nitration of aniline using concentrated $HNO_3$ and $H_2SO_4$ at $288 \ K$,the amino group $(-NH_2)$ is protonated to form the anilinium ion $(-NH_3^+)$ in the acidic medium. The $-NH_3^+$ group is meta-directing,which leads to a significant amount of meta-nitroaniline $(B)$. However,some unprotonated aniline also reacts,leading to ortho $(A)$ and para $(C)$ products. The experimental percentage yields are approximately: $p$-nitroaniline $(C)$ $\approx 51\%$ $m$-nitroaniline $(B)$ $\approx 47\%$ $o$-nitroaniline $(A)$ $\approx 2\%$ Thus,the order of percentage yield is $C > B > A$.

Consider the given reaction,find the correct order of percentage yield for the products $A$,$B$,and $C$:
