Question

The following structure represents: $R_2C=N-OH$

• A. An oxime
• B. A hydrazone
• C. An imine
• D. A Schiff's base

Hint:

Oxime: $C=N-OH$. Hydrazone: $C=N-NH_2$. Imine: $C=N-R$.

Answer 1

The Correct Option is A

Step 1: Concept
Organic compounds are classified based on their functional groups.

Step 2: Meaning
The general formula $R_2C=N-OH$ (where $R$ can be $H$ or an alkyl group) is the characteristic structure of an oxime.

Step 3: Analysis
Oximes are formed by the reaction of aldehydes or ketones with hydroxylamine ($NH_2OH$). If formed from an aldehyde, it's an aldoxime; from a ketone, it's a ketoxime.

Step 4: Conclusion
The structure containing the $C=N-OH$ group is explicitly an oxime. Final Answer: (A)
