Vedclass · Accepted Answer

There is no fundamental difference between them; they are often used interchangeably to describe the delocalization of $\pi$-electrons.

Vedclass · Answer

(C) The terms $Mesomeric \ effect$ and $Resonance \ effect$ are often used interchangeably in organic chemistry. Both refer to the delocalization of $\pi$-electrons or lone pairs of electrons through a conjugated system. While some textbooks distinguish them by stating that the $Mesomeric \ effect$ is specifically used for substituents attached to a conjugated system (like $-OH, -NH_2$),the underlying electronic mechanism is identical to $Resonance$.
