Sulphur has greater tendency for catenation than oxygen why? |
| Answer» Solution :Bond ENERGY of `S-S` bond `("213 KJ mol"^(-1))` is GREATER than `O-O` bond `("138 KJ mol"^(-1))`. Due to small size of oxygen ATOM there is greater lp - bp repulsion in `O-O`, resulting in weakening of `O-O` bond more than in `S-S` bond. THEREFORE the tendency of catenation in Oxygen is lower than sulphur. | |
