Question

A substance C\(_4\)H\(_8\)O yields on oxidation a compound, C\(_4\)H\(_8\)O\(\) which gives an oxime and a positive iodoform test. The original substance on treatment with conc. H\(_2\)SO\(_4\) gives C\(_4\)H\(_8\). The structure of the compound is

• A. CH\(_3\)COCH\(_2\)OH
• B. CH\(_3\)COOH
• C. CH\(_3\)COCH\(_2\)CH\(_3\)
• D. CH\(_3\)CH\(_2\)OH

Hint:

The positive iodoform test is a characteristic of compounds with a methyl group attached to a carbonyl group.

Answer 1

The Correct Option is A

Step 1: Analyze the oxidation and tests.
The given tests (iodoform and oxime) suggest that the original compound is acetaldehyde, which on oxidation gives acetic acid.
Step 2: Conclusion.
Thus, the compound is CH\(_3\)COCH\(_2\)OH.
Final Answer: \[ \boxed{\text{CH}_3\text{COCH}_2\text{OH}} \]
