The correct order of acidic strength of the following is
(I) Oxalic acid HOOC - COOH
(II) Malonic acid HOOC - CH 2 - COOH
(III) Succinic acid HOOC - (CH 2 ) 2 - COOH
(IV) Glutaric acid HOOC - (CH 2 ) 3 - COOH
Text Solution
Verified by ExpertsThe correct answer is:
A
Acidic strength of dicarboxylic acid is based on the +1 effect of alkyl group. As +1 increases acidic nature decreases. Compounds with formula HOOC - (CH 2 ) n - COOH are called dicarboxylic acid. Acidic strength order is: Oxalic acid > Malonic acid > Succinic acid > Glutaric acid
