Solution

The correct option is B Electronegativity
The polarity of a bond can be explained by electronegativity.
When the two atoms joined by a covalent bond have the same electronegativity, the bond is the non polar covalent bond.
When the two atoms joined by a covalent bond have different electronegativity, the bond is the polar covalent bond.

"The acidic nature of alcohols is due to the polar nature of OH bond. And electron releasing group (-CH3, -C2H5) increases electron density on oxygen tending to decrease the polarity of O-H bond."

Please explain how increase in electron density on Oxygen atom decreases polarity.

Q. Assertion :A nonpolar molecule can have polar bonds.
Reason: Polar bonds can be symmetrically arranged in a molecule so that there are no net poles.

why does an electron releasing group decrease polarity of bonds

Explain with the help of a suitable example polar covalent bond.
