1.	Explain why bond angle in NH3 is more than in H2O molecules though both have SP3 hybridization?
Answer» In H2O oxygen has two lone pairs and two H both lp take more space than the h bonds and ita angle dec. to 104.5. In NH3 1 lp+ three h bonds less lp space as being one so inc.angle to 107 Lp occupy more space than bonds Because oxygen have only two surrounded atoms while nitrogen has three surrounded atoms .Also i think oxygen is more electrongative , so its electronegativity may effect the bond angle.
