Interpretation Introduction

Interpretation:

The diatomic molecule that is polar has to be chosen from the given options.

Concept Introduction:

Measure of the degree of inequality in attraction of the bonding electrons to the various locations present within a molecule is known as molecular polarity.  This can also be said in terms of electron attraction and that is in a molecule one part is favored than the other parts of the molecule.

If in a molecule there is an uneven distribution of electronic charges means it is known as polar molecule.  If there is a symmetrical distribution of electron charge over the molecule means it is known as nonpolar molecule.  Two factors that decide molecular polarity is bond polarity and geometry of molecule.  If a molecule is symmetrical means then there won’t be any molecular polarity because the effect given by the polar bonds may cancel out each other.
