| ii. | The aqueous solution of phenol turns blue litmus to red, i.e., phenol is weakly acidic. | The aqueous solution of ethyl alcohol is neutral to litmus, i.e, ethyl alcohol is neutral. |
| iii. | Phenol reacts with aqueous NaOH to form sodium phenoxide. | Ethyl alcohol does not react with aqueous NaOH. |
| iv. |
Phenol reacts with neutral ferric chloride solution to give deep purple colouration of ferric phenoxide. |
Ethyl alcohol does not react with neutral ferric chloride. |
