Question:
Which of the following is obtained on dry distillation of equimolar mixture of calcium acetate and calcium propionate?
Which of the following is obtained on dry distillation of equimolar mixture of calcium acetate and calcium propionate?
Show Hint
When equimolar mixtures of calcium salts like acetate and propionate undergo dry distillation, ketones like ethyl methyl ketone are formed.
Updated On: Feb 18, 2026
- Ethyl propyl ketone
- Propionaldehyde
- Acetaldehyde
- Ethyl methyl ketone
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the reaction.
When calcium acetate and calcium propionate undergo dry distillation, they form ketones and aldehydes. Ethyl methyl ketone is formed when the mixture is heated.
Step 2: Analyzing the options.
(A) Ethyl propyl ketone: This is not the product of this reaction.
(B) Propionaldehyde: This is also not the correct product.
(C) Acetaldehyde: Acetaldehyde is not formed from this reaction either.
(D) Ethyl methyl ketone: This is the correct product formed from dry distillation of calcium acetate and calcium propionate.
Step 3: Conclusion.
The correct answer is (D) Ethyl methyl ketone.
When calcium acetate and calcium propionate undergo dry distillation, they form ketones and aldehydes. Ethyl methyl ketone is formed when the mixture is heated.
