Ethyl alcohol on oxidation with PCC gives ____________.

Options

A. acetone
B. acetaldehyde
C. ether
D. ethylene

Answer

To solve the question "Ethyl alcohol on oxidation with PCC gives ____________," we can follow these steps:

### Step 1: Identify Ethyl Alcohol
Ethyl alcohol is also known as ethanol, which has the chemical formula C2H5OH.

### Step 2: Understand the Oxidizing Agent
Pyridinium chlorochromate (PCC) is a mild oxidizing agent. It is used to oxidize alcohols without over-oxidizing them to carboxylic acids.

### Step 3: Determine the Type of Alcohol
Ethanol (ethyl alcohol) is a primary alcohol. When primary alcohols are oxidized by PCC, they are converted to aldehydes.

### Step 4: Perform the Oxidation Reaction
When ethanol (C2H5OH) is oxidized by PCC, the hydroxyl group (-OH) is converted to a carbonyl group (C=O), resulting in the formation of acetaldehyde (also known as ethanal), which has the formula CH3CHO.

### Step 5: Write the Final Answer
Thus, the oxidation of ethyl alcohol (ethanol) with PCC gives acetaldehyde.

### Final Answer:
Ethyl alcohol on oxidation with PCC gives **acetaldehyde**.
