Synthesise the following :
Benzyl alcohol from `G.R`.

Explanation

To synthesize benzyl alcohol from a Grignard reagent, we can follow these steps:

### Step 1: Prepare the Grignard Reagent
- Start by preparing the Grignard reagent. In this case, we will use phenylmagnesium bromide (PhMgBr).
- This is done by reacting bromobenzene (C6H5Br) with magnesium (Mg) in dry ether. The reaction can be represented as:
\[ C_6H_5Br + Mg \xrightarrow{\text{dry ether}} C_6H_5MgBr \]
