Oxygen shows catenation behaviour less than sulphur. |
| 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. | |
