Question

Polarity of bonds and molecules is determined by the ______________ of the atoms involved.

Answer 1

Symmetry of the atoms

Answer 2

Explanation:

Polarity is defined as the formation of opposite charges on the atoms of a compound due to the difference in their electronegativities.

For example, in a HCl molecule chlorine is more electronegative in nature as compared to the hydrogen atom.

Hence, chlorine will attract the valence electron of hydrogen atom more towards itself. Due to this a partial positive charge will develop on hydrogen atom and a partial negative charge will develop on the chlorine atom.

Thus, we can conclude that polarity of bonds and molecules is determined by the difference in electronegativity of the atoms involved.
