Is there a qualitative reason for this? The bond angle of Cl2O is larger than H2O because in case of Cl, P double bonds can be formed as they can expand their shells , double bonds cause more repulsions , and hence bond angle increases. The bond angle between H—C—H is 109.5° which is called the tetrahedral angle. Anonymous User Chemistry 27 Aug, 2019 1670 views. Based on the bond angles in CH4 , NH3 , and H2O, rank the magnitude of these repulsions. Favorite Answer. 0 0. In H2O, H2S, H2Se, H2Te, the bond angle decreases though all have the same bent shape. (c) SF6 is inert and stable but SF4 is reactive. Among the hydrides, H2O, H2S, H2Se which has highest bond angle. Due to more electronegativity of oxygen electron cloud shift towards it and this lead to increase in b.p-b.p repulsion. Still have questions? 1 Answer +1 vote . Firstly, ‘S’ in SO2 is sp2 hybridised ,and central atoms of H2O,H2S and NH3 are sp3 hybridised.So, the bond angle in case of SO2 is nearly 120 degree, whereas the bond angles in case of H2o,H2S and NH3 are nearly equal to 109.5 degree.
