The decreasing order for the acidic strength of 1^ , 2^ , 3^ alcohols, H_2O and RC CH is

MHT CET Chemistry question

The decreasing order for the acidic strength of alcohols, and is

(A) alcohols alcohols alcohols
(B) alcohols alcohols alcohols alcohols
(C) alcohols alcohols alcoholsCorrect
(D) alcohols alcohols alcohols > RC\equiv CH > H_2O > RC\equiv CH

Answer: (C)

Solution

Alkyl groups (+I effect) destabilise the alkoxide ion, so acidity falls in the order water > 1° > 2° > 3° alcohols, and all of these are far more acidic
