An organic (A) reacts with `PCl_(5) ` to produce another compound (B). (B) reacts with magnesium metal in presence of ether to produce a Grignard reagent (C). (C) reacts with ethanal and the3 product is hydrolysed to produce propan-2-ol. Identify (A), (B) and (C) and explaiin the reactions.

Explanation

To solve the problem step by step, we need to identify the compounds A, B, and C based on the reactions described.

### Step 1: Identify Compound A
The problem states that an organic compound (A) reacts with phosphorus pentachloride (PCl₅) to produce another compound (B). PCl₅ is commonly used to convert alcohols into alkyl chlorides. Therefore, compound A is likely an alcohol.

Given that the final product after hydrolysis is propan-2-ol, we can deduce that A must be an alcohol that can lead to the formation of propan-2-ol after a series of reactions. The simplest alcohol that fits this description is **isopropyl alcohol (propan-2-ol)**.

However, to produce propan-2-ol, A should be **isopropyl alcohol (C₃H₈O)**.
