Which one of the following hydrides has largest bond angle ? H_(2)O, H_(2)S, H_(2)Se or H_(2)Te |
| Answer» Solution :As the electronegativity of the central atom decreases, the bond pairs of electrons TEND to lie away and away from the central atom as we move from `H_(2)O` to `H_(2)Te`. In other words, the FORCE of repulsion between the ADJACENT bond pairs is maximum in `H_(2)O` and minimum in `H_(2)Te`. THUS, `H_(2)O` has the largest bond ANGLE `(104.5^(@))`. | |
