Question

Inductive effect involves

• A. displacement of $\sigma$ electron
• B. delocalisation of $\pi$ electrons
• C. delocalisation of $\sigma$ electrons
• D. displacement of $\pi$ electrons

Answer 1

Answer: (A)

displacement of $\sigma$ electron

Answer 2

The correct answer is A displacement of $\sigma$ electron

The inductive effect helps spread the unequal sharing of the bonding electron through the atoms in a chain of the molecule. This leads to the formation of a dipole in a bond. This distribution of electrons is also called displacement of electrons.

In an inductive effect, the sigma (σ) electrons are getting displaced resulting in the polarization of the bond. The inductive effect is the polarization of a σ bond due to the presence of an electron-withdrawing or an electron-donating group or atoms in a molecule. During the inductive effect, shifting of electrons takes place due to which partial charges occur on the atom.
