Explanation The methane molecule may be assumed to have bond angle of 90°instead of 109.5°considering it to be planar with a square planar geometry. It may be assumed that the bond is formed between three p orbitals of carbon and s orbital of hydrogen with all the bond angles of 90°. However, this is not the case as the four three sp 3 lops directing out to bond with hydrogen and every lop has 2e - , so repulsion occur...
