It is generally seen that the geometrical shape of polar molecules is asymmetric(distorted) due to which the charge disperses unevenly on the molecule. It is volatile in nature and reacts vigorously with water to produce HCl gas. In CCl4, each chlorine is somewhat negative but the symmetry of the molecule means that the molecule itself is non-polar. If I talk about the bond distance, so it’s the distance between the central part and the other two bonded atoms which is joining the center along a straight line. Let us know in the comments section below we will add them. Using electronegativity values, the P-Cl bonds in in PCl3 are _____.
