Vedclass · Answer

(D) $o$-hydroxybenzaldehyde $(A)$ exhibits intramolecular $H$-bonding,which leads to the formation of a stable chelate ring within the molecule. This restricts the association between different molecules.In contrast,$p$-hydroxybenzaldehyde $(B)$ exhibits intermolecular $H$-bonding,which allows for strong association between different molecules,resulting in a higher melting point.Therefore,the lower melting point of $(A)$ is due to the presence of intramolecular $H$-bonding,while $(B)$ has intermolecular $H$-bonding.

The melting point of $o$-hydroxybenzaldehyde $(A)$ is lower than that of $p$-hydroxybenzaldehyde $(B)$. This is because
