Options:
- Salicylic acid
- Salicylaldehyde
- Quinol
- Catechol
Show Hint
Intramolecular H-bonding depends on proximity of H donor and acceptor groups in molecule.
Updated On: Jun 4, 2025
- Salicylic acid
- Salicylaldehyde
- Quinol
- Catechol
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Intramolecular H-bonding
Occurs when H-bond forms within the same molecule between H and electronegative atom.
Step 2: Compound analysis
- Salicylic acid, Salicylaldehyde, and Catechol have intramolecular H-bonding due to -OH and -COOH or -CHO groups proximity.
- Quinol lacks suitable groups for intramolecular H-bonding; its H-bonds are intermolecular.
Step 3: Conclusion
Quinol does not exhibit intramolecular H-bonding.
