Question

why Sigma bonded electron participates in inductive effect

Answer 1

Electronegativity cause delocalise the electron ty bond is more expands within molecule Sigma bond is more strong than other bond

Answer 2

In chemistry, the inductive effect is an effect regarding the transmission of unequal sharing of the bonding electron through a chain of atoms in a molecule, leading to a permanent dipole in a bond. It is present in a σ (sigma) bond as opposed to electromeric effect which is present on a π (pi) bond.
