Question:
Acetone on heating with \(\text{CrO}_3\) mainly forms,
Acetone on heating with \(\text{CrO}_3\) mainly forms,
Show Hint
Strong oxidation of a ketone breaks a C-C bond and gives acids.
Updated On: Oct 1, 2026
- Acetic acid
- Ethyl alcohol
- Toluene
- Dimethyl ether
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Ketone oxidation
Ketones resist mild oxidants but under vigorous conditions, such as hot \(CrO_3\), the C-C bond next to the carbonyl breaks.
Step 2: Acetone
Acetone \(CH_3COCH_3\) breaks to give acetic acid (and carbon dioxide on further oxidation of the other fragment). So the main organic product is acetic acid.
Step 3: Other options
Ethyl alcohol, toluene and dimethyl ether are not oxidation products of a ketone.
Final Answer:
Acetone on strong oxidation mainly gives acetic acid. \[ \boxed{\text{(A)}\ \text{Acetic acid}} \]
