| I: | The product of the reaction of phenol with bromine depends on the nature of the solvent. |
| II: | The reaction of phenol with bromine in CHCl3 gives a monosubstituted bromo derivative whereas the reaction of phenol with bromine water yields a trisubstituted bromo derivative of phenol. |
In light of the above statements, choose the most appropriate answer from the options given below:
| 1. | I is correct and II is incorrect |
