Vedclass · Answer

(D) The stability of carbocations is determined by factors like resonance,hyperconjugation,and inductive effects. In the given options,the cation where the positive charge is adjacent to the $-OH$ group is the most stable. This is because the lone pair of electrons on the oxygen atom of the $-OH$ group can delocalize into the ring,forming a resonance structure where the oxygen atom carries a positive charge and is bonded to the ring by a double bond. This structure is highly stable because every atom (including the oxygen atom) has a complete octet. This is represented by the resonance structure $C_6H_6OH^+$ where the positive charge is on the oxygen atom. Therefore,the cation that allows for this specific resonance stabilization is the most stable.

$B$. Eclipsed and staggered ethane	$2$. Tautomers
$C$. $(+)2$-butanol,$(-)2$-butanol	$3$. Chain isomers
$D$. Methyl-$n$-propylamine and diethylamine	$4$. Conformational isomers
	$5$. Metamers
