In A level chemistry, presence of -OH gives a higher electron density as lone pair from O joins delocalised ring. Also increases solubility as it can form H bonds with water.
Reactions to form salts
- With NaOH: C6H5OH + NaOH -> C6H5O-Na+ + H2O
- With Na: 2C6H5OH +2Na -> 2C6H5O-Na+ + H2
You need to remember two main points of Bromination in A level chemistry curriculum:
- Reacts at room temp with no heat to form 2,4,6-tribromophenol
- Increased reactivity due to -OH lone pair and inc e- density which is able to depolarise Br2
There are some application of phenol in A level chemistry : Antiseptics, paint resins, detergent, asprin
