Question

Suggest the possible shapes of the following molecules:
H2S, BrF5, C2H4, HC1 and HgCl2

Answer 1

1.S has 6 valence electrons, out of which two are involved in the formation of the two S-H bonds,which leaves 2 lone pairs,preventing the bonding electrons from forming a linear configuration.Thus,acquiring a V-shape with about 92º between the two S-H bonds.
2.It has a square pyramidal shape with about 90º of bond angle of F-B-F covalent bond.
3.It is not confirmed but is predicted to be a trigonal planar molecular geometry.
4.It has a linear shape.
5.It has a linear shape.

Hope it helps!!!
