Statement 1: Diisopropyl ketone on reaction with isopropyl magnesium bromide followed by hydrolysis gives `2^(@)` alcohol.
Statement 2: Grignard reagent acts as a reducing agent.

Options

A. a.Statement 1 and Statement 2 are true and Statement 2 is the correct explanation of Statement 1.
B. b.Statement 1 and Statement 2 are true and Statement 2 is not the correct explanation of Statement 1.
C. c.Statement 1 is true and statement 2 is false.
D. d.Statement 1 is false and statement 2 is false

Explanation

To solve the question, we will analyze both statements provided and provide a step-by-step explanation of the chemical reaction involved.

### Step 1: Understanding Diisopropyl Ketone
Diisopropyl ketone (also known as 3-pentanone) has the following structure:

```
CH3
|
CH3-C-CH2
||
O
```

In this structure, the carbonyl group (C=O) is attached to a carbon atom that is also bonded to two isopropyl groups (CH(CH3)2).

### Step 2: Reaction with Isopropyl Magnesium Bromide
Isopropyl magnesium bromide (a Grignard reagent) has the following structure:

```
CH3
|
CH3-C-MgBr
```

When diisopropyl ketone reacts with isopropyl magnesium bromide, the Grignard reagent acts as a nucleophile. The carbonyl carbon of the ketone is electrophilic and will react with the nucleophilic carbon of the Grignard reagent.

### Step 3: Nucleophilic Attack
The nucleophilic carbon from the Grignard reagent attacks the carbonyl carbon, resulting in the formation of a tetrahedral intermediate. This intermediate can be represented as:

```
CH3
|
CH3-C-O-MgBr
|
CH2
```

### Step 4: Hydrolysis
Upon hydrolysis (addition of water), the magnesium bromide leaves, and a hydroxyl group (-OH) is formed. The final product is a secondary alcohol:

```
CH3
|
CH3-C-OH
|
CH2
```

This compound is diisopropyl alcohol, which is a secondary alcohol because the carbon attached to the hydroxyl group is bonded to two other carbon atoms.

### Step 5: Conclusion on Statements
- **Statement 1**: Diisopropyl ketone on reaction with isopropyl magnesium bromide followed by hydrolysis gives a secondary alcohol. This statement is **correct**.
- **Statement 2**: Grignard reagent acts as a reducing agent. This statement is also **correct** because it provides a hydride ion (H-) that reduces the ketone to an alcohol.

### Final Answer
Both statements are correct, and statement 2 provides the correct explanation for statement 1. Therefore, the answer is option A.
