In H2S, the H − S − H bond angle is 92.2º while in H2O,The H − O − H bond angle is 104.5º why?

Answer»

H2S is less polar than H2O because Sulphur is bigger in size and has less electronegativity. So, bp-bp repulsion is less in H2S as compared to H2O Hence, bond angle of H − S − H in H2S, is lesser than H2O.
