An alkyl halides (P) reacts with magnesium metal in presence of dry ether followed by treatment of ethanol gives propane. Write the structure of the alkyl halide (X).

Explanation

To determine the structure of the alkyl halide (P) that reacts with magnesium metal in dry ether and subsequently with ethanol to yield propane, we can follow these steps:

### Step 1: Understand the Reaction
The alkyl halide (P) reacts with magnesium in dry ether to form a Grignard reagent (RMgX). This Grignard reagent is then treated with ethanol (C2H5OH) to produce propane (C3H8).

### Step 2: Identify the Product
The product of the reaction is propane (C3H8), which has the structure:
