Question:
Identify false statements regarding the properties of alcohol and phenol.
Identify false statements regarding the properties of alcohol and phenol.
Show Hint
Both alcohols and phenols contain an OH group and do form intermolecular hydrogen bonds.
Updated On: Nov 12, 2026
- Aqueous solution of alcohol is neutral to litmus.
- An aqueous solution of phenol turns blue litmus red.
- Alcohols and phenols do not form intermolecular hydrogen bonds.
- Phenols and lower alcohols have appreciable solubility in water.
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept
We must pick the statement that is false.
Step 2: Check Each Statement
(A) Alcohol solutions are neutral to litmus - true.
(B) Phenol is acidic and turns blue litmus red - true.
(D) Phenol and lower alcohols dissolve in water due to hydrogen bonding - true.
Step 3: False Statement
(C) Alcohols and phenols have \(-\text{OH}\) groups, so they do form intermolecular hydrogen bonds. This statement is false.
Step 4: Compare the options
The false statement is option (C).
Final Answer:
Alcohols and phenols do form hydrogen bonds, so statement C is false. \[ \boxed{\text{(C) }\text{Alcohols and phenols do not form intermolecular hydrogen bonds.}} \]
