Question

Why primary alcohol is more acidic than secondary and tertiary alcohol?

Answer 1

Answer:

. The acidic character of alcohols is due to the polar nature of O–H bond. An electron-releasing group increases electron density on oxygen tending to decrease the polarity of O-H bond.

The number of electron-releasing groups decreases in the order tertiary alcohol > secondary alcohol >primary alcohol

Thus the acidic strength decreases in the order:

CH3CH2OH > (CH3)2CHOH > (CH3)3COH

(Primary) (Secondary) (Tertiary)

Hope this clears your confusion
