Question

Which of the following is obtained on alkaline hydrolysis of 1,1-dichlorocyclohexane?

• A. Cyclohexanol
• B. Cyclohexanone
• C. Benzaldehyde
• D. Cyclohexane carbaldehyde

Hint:

Alkaline hydrolysis of dichlorocyclohexane typically leads to the formation of cyclohexanone, a common product of such reactions.

Answer 1

The Correct Option is B

Step 1: Understanding the reaction.
Alkaline hydrolysis of 1,1-dichlorocyclohexane leads to the formation of cyclohexanone. The chlorine atoms are replaced with hydroxyl groups, and the product is a ketone.
Step 2: Analyzing the options.
(A) Cyclohexanol: Incorrect. Cyclohexanol is an alcohol, not a ketone, and it is not produced from this reaction.
(B) Cyclohexanone: Correct — Cyclohexanone is formed by the alkaline hydrolysis of 1,1-dichlorocyclohexane.
(C) Benzaldehyde: Incorrect. This is an aromatic aldehyde, not a product of the given reaction.
(D) Cyclohexane carbaldehyde: Incorrect. Cyclohexane carbaldehyde is not the product of this hydrolysis reaction.
Step 3: Conclusion.
The correct answer is (B) Cyclohexanone. The reaction leads to the formation of a ketone, not an alcohol or aldehyde.
