Question

1.Arrange the following compounds in
increasing order of their acid strength:
Propan-1-ol, 2,4,6-trinitrophenol, 3-
nitrophenol. 3,5-dinitrophenol, phenol, 4
methylphenol.
Your answer​

Answer 1

Answer:

The increasing order of acidic strength is :

Propan-1-ol < 4-methylphenol < 3-nitrophenol < phenol < 3, 5-dinitrophenol < 2, 4, 6-trinitrophenol.

Explanation:

The increasing order of acidic strength is based upon the following facts about the acidic strengths of alcohols and phenols.

∗ Phenol is a stronger acid than alcohol.

∗ Methyl (−CH3) group being electron releasing in nature, decreases the acidic strength of phenol.

∗ Nitro (−NO2) group being electron withdrawing in nature, increases the acidic strength of phenol.
