Description : Suggest the expected shape of the following molecules with reasons a.SO2 b.NH3
Last Answer : Ans.(a) In SO2 molecule there are three electron pairs .the three electron pairs should acquire trigonal planar arrangement with bond angle 120 ° .Since one of the position is occupied by lone pair the geometry ... to 107 ^0 from 109.5^ 0 and hence the geometry of ammonia is regarded as pryamidal.
