Mesomeric effect involves delocalisation of

A

pi electrons

B

sigma electrons

C

protons

D

none of these

Answer

pi electrons

Explanation

Solution

The mesomeric effect involves the complete transfer or release of π\pi or lone pair of electronsto the adjacent atom or covalent bond. Therefore, it involves the delocalization of pi (π)(\pi) electrons.

Mesomeric effect involves the delocalization of π electrons. Hence option A is correct.
