What are correct steps to convert acetaldehyde to acetone?

Options

A. `CH_(3)MgBr,H_(2)O`,Oxidation
B. Oxidation, `Ca(OH)_(2)`, Heat
C. Reduction, KCN, Hydrolysis
D. Oxidation `C_(2)H_(5)`ONa, heat

Explanation

To convert acetaldehyde (CH3CHO) to acetone (CH3COCH3), we can follow these steps:

### Step 1: Oxidation of Acetaldehyde
- The first step is to oxidize acetaldehyde (CH3CHO) to acetic acid (CH3COOH). This can be achieved using an oxidizing agent such as potassium dichromate (K2Cr2O7) in acidic medium or other suitable oxidizing agents.

### Step 2: Conversion of Acetic Acid to Acetone
- The next step is to convert acetic acid (CH3COOH) to acetone (CH3COCH3). This can be done through a process called decarboxylation.
- One common method is to use the reaction of acetic acid with a strong base like sodium hydroxide (NaOH) followed by heating. This process generates acetone.

### Summary of Steps
1. **Oxidation of Acetaldehyde to Acetic Acid:**
\[ \text{CH}_3\text{CHO} \xrightarrow{\text{Oxidizing Agent}} \text{CH}_3\text{COOH} \]

2. **Decarboxylation of Acetic Acid to Acetone:**
\[ \text{CH}_3\text{COOH} \xrightarrow{\text{NaOH, heat}} \text{CH}_3\text{COCH}_3 \]

### Final Product
- The final product after these steps is acetone (CH3COCH3).
