Q. Assertion :Both o-hydroxy benzaldehyde and p-hydroxy benzaldehyde have same molecular weight and show H-bonding. Reason: Melting point of p-hydroxy benzaldehyde is more than o-hydroxy benzaldehyde.

Q. In which case first has higher solubility than second?
(I) Phenol, Benzene
(II) Nitrobenzene, Phenol
(III) o-Hydroxybenzaldehyde, p-Hydroxy benzaldehyde
(IV)

C H_{3} C H O, C H_{3} - O - C H_{3}

(V) o-Nitrophenol, p-Nitrophenol

Q. o-hydroxybenzadehyde is a liquid at room temperature while p-hydroxybenzaldehyde is high melting solid because there is intramolecular H-bonding in o-hydroxybenzaldehyde (weak) while intermolecular H-bonding in p-isomer (strong).
