How wil l you convert ethyl cyanide to 1- phenylpropanone?

Explanation

To convert ethyl cyanide to 1-phenylpropanone, we will follow a systematic approach using Grignard reagents. Here’s a step-by-step solution:

### Step 1: Understanding the Reactants
- Ethyl cyanide (also known as ethyl carbamate) has the structure CH3CH2C≡N. It consists of an ethyl group attached to a cyano group (–C≡N).

### Step 2: Prepare the Grignard Reagent
- We will prepare the Grignard reagent by reacting bromobenzene with magnesium in dry ether. The Grignard reagent formed will be phenyl magnesium bromide (C6H5MgBr).
