Phosphorus trihydride, commonly known as phosphine (PH 3 ), is a polar molecule. It consists of three P-H bonds. P-H bonds are slightly polar almost nonpolar according to Pauling scale, with an electronegativity difference of only 0.01 units between the bonded P-atom (E. N= 2.19) and H-atom (E. N= 2.20).
