Assertion: Oximes are less acidic than hydroxyl amine.
Reason: Oximes of aldehydes and ketones show geometrical isomerism.

Options

A. If both assertion and reason are true and the reason is the correct explanation of the assertion
B. If both assertion and reason are true but reason is not the correct explanation of the assertion
C. If assertion is true but reason is false
D. If assertion is false but reason is true

Explanation

To solve the question regarding the assertion and reason about oximes and hydroxylamine, let's break it down step by step.

### Step 1: Understand the Assertion
**Assertion:** Oximes are less acidic than hydroxylamine.

- **Explanation:**
- Hydroxylamine (NH2OH) has an acidic hydrogen atom on the hydroxyl (-OH) group. When this hydrogen is removed, it forms a stable conjugate base due to resonance stabilization.
- Oximes (R1R2C=NOH) have a hydroxyl group attached to a carbon-nitrogen double bond. The acidic hydrogen in oximes is on the hydroxyl group as well, but the conjugate base formed after deprotonation is less stable compared to that of hydroxylamine. This is due to the lack of resonance stabilization in the oxime's conjugate base.
