Q8.5(ii):
Draw structures of the following derivatives.
(ii) Cyclopropanone oxime
Solution :
Step 1: Structural Identification of the Parent Carbonyl
The parent molecule is cyclopropanone. Cyclopropanone consists of a three-membered carbon ring where one carbon atom is part of a carbonyl group ($C=O$).
- Molecular Formula of Cyclopropanone: $C_3H_4O$.
- Functional Group: Ketone moiety at the $C_1$ position of the cyclopropane ring.
Step 2: Mechanism of Oxime Formation
An oxime is formed via the nucleophilic addition-elimination reaction between a carbonyl compound and hydroxylamine ($NH_2OH$). [Per the Nucleophilic Addition Mechanism to Carbonyls].
The reaction proceeds as follows:
$\text{R}_2C=O + H_2N-OH \rightarrow \text{R}_2C=N-OH + H_2O$
In the case of cyclopropanone, the oxygen atom of the carbonyl is replaced by the $=N-OH$ (oxime) group while maintaining the cyclic structure.
Step 3: Geometrical Configuration
The oxime functional group exhibits $sp^2$ hybridization at the carbon atom. The nitrogen atom is double-bonded to the ring carbon and single-bonded to a hydroxyl group ($-OH$). The structure is planar at the imine bond.
Step 4: Structural Representation (SVG)
Step 5: Chemical Formula and Structural Summary
The structure consists of a cyclopropane ring substituted at the $1$-position with an $=N-OH$ group.
| Component | Description |
|---|---|
| IUPAC Name | Cyclopropanone oxime |
| Chemical Formula | $C_3H_5NO$ |
| Hybridization (C=N) | $sp^2$ |
Final Solution: The structure of cyclopropanone oxime is a three-membered cyclopropane ring containing a $C=N-OH$ functional group at the carbon formerly bonded to the carbonyl oxygen.

A Highly talented Chemistry teacher with excellent communication skills demonstrated by 11 years of teaching experience. Strong theoretical and good knowledge of Chemistry. A good Communication skills to maintain great relationship with students and ability to work well with others. You Can also watch me on my YouTube channel L.k.Soni Chemistry Classes.

I had the opportunity to attend one-on-one Classes for class 12 CBSE Chemistry with him, and the experience was excellent. His way of explaining concepts is very clear, simple, and easy to understand. He makes sure that every doubt is addressed patiently and focuses not just on memorising reactions and formulas, but on developing a proper understanding of the concepts. I especially appreciated his exam-oriented approach, which makes difficult topics feel much more manageable and helps build confidence for the CBSE Board exams. He is very knowledgeable, supportive, and genuinely dedicated to his students. I would highly recommend his classes to any Class 12 CBSE Chemistry student looking for strong conceptual clarity and effective preparation.
