The melting point of o-hydroxybenzaldehyde \((\mathrm{A})\) is lower than that of p-hydroxybenzaldehyde (B). This is because
- A (A) has intermolecular H-bonding and (B) has intramolecular H -bonding
- B Both (A) and (B) have intermolecular H-bonding
- C Both (A) and (B) have intramolecular H -bonding
- D (A) has intramolecular H-bonding and (B) has intermolecular H -bonding
Answer & Solution
Correct Answer
(D) (A) has intramolecular H-bonding and (B) has intermolecular H -bonding
Step-by-step Solution
Detailed explanation
Intramolecular H -bonding have low melting point due to chelation between aldehyde and hydroxyl group so its melting point is lower as compare to intermolecular H -bonding.
