Question

A carbonyl compound X (\( C_3H_6O \)) on oxidation gave a carboxylic acid Y (\( C_3H_6O_2 \)). Oxime of X is:

• A.

  

• B.

  

• C.

  

• D.

  

Hint:

Oximes are obtained by reacting aldehydes or ketones with hydroxylamine (\( NH_2OH \)).

Answer 1

The Correct Option is C

Step 1: Identifying the Carbonyl Compound X - Given that oxidation of \( X \) gives a carboxylic acid (\( C_3H_6O_2 \)), 
- This suggests that \( X \) must be a ketone or aldehyde that can be oxidized to a carboxylic acid. 

Step 2: Checking Possible Structures - The simplest possible ketone or aldehyde with \( C_3H_6O \) is propanal or propanone. 
- Since oxidation leads to a single carboxylic acid, the compound must be propanal (CH\(_3\)-CH\(_2\)-CHO). 

Step 3: Identifying the Oxime of X 
- The oxime is formed when aldehydes react with hydroxylamine (NH\(_2\)OH). 
- This results in the formation of propanal oxime (CH\(_3\)-CH\(_2\)-CH=NOH).
