In a molecule of PCl3, 6 electrons will form

A) nonpolar covalent bonds

B) polar covalent bonds

C) ionic bonds

D) hydrogen bonds

polar covalent bonds

Explanation:

Phosphorus trichloride is a chemical compound of phosphorus and chlorine, having the chemical formula PCl 3. It has a trigonal pyramidal shape, owing to the lone pairs of electrons on the phosphorus atom.

Chlorine is more elctronegative than phosphorus. Phosphorus has a lone pair of electrons and every chlorine atom has three pairs of electrons. The molecule is not symmetrical as the shared electron pairs are closer to the chlorine atoms than the phosphorus atoms, the chlorine atoms are shifted towards one side of the center of the molecule, thus a net dipole effect is created. This is the reason why the molecule is polar.
