Question

Which statement justifies that phosphine (PH3) is a polar molecule? The P-H bond is nonpolar and the molecule is asymmetric. The P-H bond is nonpolar and the molecule is symmetric. The P-H bond is polar and the molecule is asymmetric. The P-H bond is polar and the molecule is symmetric. The P-H bond is polar and the charges are distributed equally

Answer 1

Phosphine is the example of a polar compound having non polar bond.

The lone pairs of electron on phosphorous causes the molecule to be assymetrical which is triagonal planar.

So the answer is PH3 is with non polar P-H bond and assymetrical.
