Identify the product `Y` in the sequence
`CH_(3) CHO + CH_(3) MgI overset (Ether) to X overset (H_(3) O^(+)) to Y`

Options

A. `CH_(3) OH`
B. `CH_(3) CH_(2) OH`
C. `CH_(3) COCH_(3)`
D. `CH_(3)OCH_(3)`

Answer

To identify the product `Y` in the given sequence, we will go through the reaction step by step.

### Step 1: Identify the Reactants
The reactants given are:
- **Aldehyde**: CH₃CHO (acetaldehyde)
- **Grignard Reagent**: CH₃MgI

### Step 2: Formation of Product X
When the aldehyde (CH₃CHO) reacts with the Grignard reagent (CH₃MgI) in the presence of ether, a nucleophilic addition reaction occurs. The nucleophile (CH₃⁻) from the Grignard reagent attacks the electrophilic carbon of the carbonyl group in the aldehyde.

1. The nucleophile (CH₃⁻) attacks the carbonyl carbon (C=O) of the aldehyde.
2. This leads to the formation of a tetrahedral intermediate, which can be represented as:
- CH₃C(OH)(CH₃) (with a negative charge on the oxygen)

This intermediate is product **X**.

### Step 3: Hydrolysis of Product X
Next, product **X** undergoes hydrolysis in the presence of H₃O⁺ (acidic conditions).

1. The oxygen in the tetrahedral intermediate (X) has a negative charge and will attract a proton (H⁺) from H₃O⁺.
2. The bond between the oxygen and the carbon will break, leading to the formation of a neutral alcohol.

### Step 4: Identify Product Y
The hydrolysis of product **X** results in the formation of a secondary alcohol.

- The structure of product **Y** can be represented as:
- CH₃CH(OH)CH₃ (which is 2-propanol or isopropyl alcohol)

### Final Answer
Thus, the product `Y` is a secondary alcohol, specifically **2-propanol**.
