Which of the following compounds does not give either a semicarbazone or an oxime?

1. HCHO
2. CH3COCH2Cl
3. CH3CHO
4. CH3CONHCH3

Correct answer: CH3CONHCH3

Solution

The compound CH3CONHCH3, which is an amide, does not react to form a semicarbazone or an oxime because these reactions typically occur with carbonyl compounds (aldehydes and ketones), while amides do not have the necessary reactive carbonyl structure to participate in these reactions.
