SF4 has a see-sawshape with a bond angle of 101. д. SF3 is a radical, and the bond angle has not been determined. The bond angles in trigonal planar are all 120°. This lone pair causes repulsion of electrons and hence causes the decrease in the normal tetrahedral angle which gets reduced to 107° in NH3 and 104.5° in H2O. Chem. Based on our data, we think this problem is relevant for Professor Tsen's class at UWATERLOO. Hint: Cl can break the octet rule.
