Vedclass · Answer

(C) Intramolecular $H$-bonding occurs when a hydrogen atom is bonded to an electronegative atom and is simultaneously attracted to another electronegative atom within the same molecule,typically forming a stable $5$ or $6$-membered ring.$1$. In $Salicylic \ acid$ ($o$-hydroxybenzoic acid),the $-OH$ group and $-COOH$ group are adjacent,allowing for intramolecular $H$-bonding.$2$. In $Salicylaldehyde$ ($o$-hydroxybenzaldehyde),the $-OH$ group and $-CHO$ group are adjacent,allowing for intramolecular $H$-bonding.$3$. In $Catechol$ ($o$-dihydroxybenzene),the two $-OH$ groups are adjacent,allowing for intramolecular $H$-bonding.$4$. In $Quinol$ ($p$-dihydroxybenzene),the two $-OH$ groups are at the $1$ and $4$ positions (para-position). Due to the large distance between the two groups,they cannot form an intramolecular $H$-bond. Instead,they exhibit intermolecular $H$-bonding.Therefore,intramolecular $H$-bonding is absent in $Quinol$.

In which of the following is intramolecular $H$-bonding absent?
