into In the light of the above statements, choose the correct answer from the options given below:
- A is true but R is false
- ) Both A and R are true and R is the correct explanation of A
- A is false but R is true
- Both A and R are true but R is NOT the correct explanation of A
The Correct Option is C
Solution and Explanation
Assertion (A):
The Wolff-Kishner reduction converts a carbonyl group (\( C=O \)) into a methylene group (\( CH_2 \)). The assertion states that 2-chloropropanal (\( \text{CH}_3\text{CHClCHO} \)) can undergo Wolff-Kishner reduction to form 2-chloropropane 
.
This assertion is false, because the Wolff-Kishner reduction would reduce the aldehyde group (\( C=O \)) to a methylene group (\( CH_2 \)), but it cannot alter or affect the chlorine substituent.
The reaction proceeds as follows:
Reason (R):
The reason states that the Wolff-Kishner reduction is used to convert \( C=O \) into \( CH_2 \). This is true and represents the principle behind the Wolff-Kishner reduction, where hydrazine (\( \text{NH}_2\text{NH}_2 \)) reacts with the carbonyl compound in the presence of a strong base like \( \text{KOH} \).
Final Answer:
A is false but R is true.

- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
