Question

What is the molecular formula of allyl chloride?

• A. \( \text{C}_3\text{H}_3\text{Cl} \)
• B. \( \text{C}_3\text{H}_5\text{Cl} \)
• C. \( \text{C}_3\text{H}_7\text{Cl} \)
• D. \( \text{C}_3\text{H}_6\text{Cl} \)

Hint:

Allyl chloride has the formula \( \text{C}_3\text{H}_5\text{Cl} \), with the chlorine attached to the terminal carbon of the allyl group.

Answer 1

The Correct Option is B

Step 1: Understanding the structure of allyl chloride.
Allyl chloride consists of a three-carbon chain (\( \text{C}_3 \)) with a chlorine atom attached to the terminal carbon. The structure is \( \text{CH}_2\text{=CH-CH}_2\text{Cl} \), giving the molecular formula \( \text{C}_3\text{H}_5\text{Cl} \).
Step 2: Conclusion.
The correct answer is (B) \( \text{C}_3\text{H}_5\text{Cl} \).
