Question

The sodium salt of which of the following acids on electrolysis produces 2-butene -
a) 1,2-dimethylmaleic acid
b) 2,2-dimethylbutanedioic aci
c) 3,3-dimethylbutanedioic acid
d) 2,3-dimethylbutanedioic aci​

Answer 1

Answer:

A)1,2- Dimethyl maleic acid

Explanation:

Kolbe Electrolysis:- The electrochemical oxidative decarboxylation of carboxylic acid salts that leads to radicals, which dimerize. It is best applied to the synthesis of symmetrical dimers, but in some cases can be used with a mixture of two carboxylic acids to furnish unsymmetrical dimers.

Also, 2,3 -Dimethyl Maleic acid will be best suited
