Out of H_2O and H_2S, which one has higher bond angle and why ? |
| Answer» SOLUTION :MOVING down the group the atomic size increases and electronegativity of central atom DECREASES. As a result, the ELECTRON density on a central atom decreases. Also, the `sp_3` CHARACTER of a bond becomes less distinct. Thus `H_2O` has a greater bond angle than `H_2S`. | |
