Options

A. Both assertion and reason are worng
B. Both assertion and reason are correct statement but reason is not correct explaination of assertion.
C. Assertion is correct statements and reason is correct explanation of assertion.
D. Both asseration and reason are correct statements and reason is correct explanation of assertion .

Explanation

To analyze the given assertion and reason, we will break down the statements and provide a step-by-step solution.

### Step 1: Understanding the Assertion
**Assertion (A)** states that N,N-diethylbenzene sulphonamide is insoluble in alkali.

- **Structure Analysis**: N,N-diethylbenzene sulphonamide consists of a benzene ring attached to a sulphonamide group (SO2NH) with two ethyl groups attached to the nitrogen atom.
- **Solubility in Alkali**: For a compound to be soluble in alkali, it typically needs to have acidic hydrogens that can react with hydroxide ions (OH-) to form soluble anions. In the case of N,N-diethylbenzene sulphonamide, there are no acidic hydrogens present on the nitrogen that can react with alkali. Therefore, it does not form any soluble species in alkaline conditions.
