Conversion of `CH_3CHO " to " (CH_3)_2 C(OH)Ph `

Explanation

To convert acetaldehyde (CH₃CHO) to 2-phenyl-2-propanol ((CH₃)₂C(OH)Ph), we will follow a multi-step synthesis involving Grignard reagents and oxidation. Here’s a step-by-step breakdown of the process:

### Step 1: Formation of Grignard Reagent
1. **Prepare the Grignard Reagent**: Start by preparing the Grignard reagent from bromobenzene (PhBr) and magnesium (Mg) in dry ether. The reaction is:
\[ \text{PhBr} + \text{Mg} \rightarrow \text{PhMgBr} \]
This gives us phenyl magnesium bromide (PhMgBr).
