Vedclass · Answer

(C) The reactivity towards $AgNO_3$ depends on the stability of the carbocation formed after the removal of the $Cl^-$ ion.$1$. Molecules $A$ and $B$ form cyclopropenyl cations upon the loss of $Cl^-$. These cations are aromatic ($2\pi$ electrons,$H$ückel's rule). The $-OCH_3$ group in $B$ provides electron density via the $+M$ effect,further stabilizing the cation compared to $A$.$2$. Molecules $C$ and $D$ form secondary carbocations. $C$ forms a $CH_3-CH^+-CH_3$ cation. $D$ forms a $CH_3-CH^+-CH_2-NO_2$ cation,which is destabilized by the strong $-I$ effect of the $-NO_2$ group.$3$. Since aromatic carbocations are significantly more stable than non-aromatic secondary carbocations,the order is $B > A > C > D$.

The decreasing order of reactivity of the following organic molecules towards $AgNO_3$ solution is:
