- A-IV, B-I, C-II, D-III
- A-III, B-IV, C-I, D-II
- A-III, B-IV, C-II, D-I
The Correct Option is D
Solution and Explanation
A: Alkaline solution of copper sulphate and sodium citrate detects aldehydes. The aldehyde reacts to form a reddish-brown precipitate of Cu$_2$O.
B: Neutral FeCl$_3$ solution is used for detecting phenolic groups. Phenols give a characteristic color (violet or blue).
C: Alkaline chloroform solution (Haloform test) detects the presence of a methyl ketone or a methyl group adjacent to a hydroxyl group.
D: Potassium iodide and sodium hypochlorite (Iodoform test) confirms alcohol groups (-CH$_3$OH). \end{itemize}

Top JEE Main Questions
- In a hydrogen like atom, when an electron jumps from the $M$ - shell to the $L$ - shell, the wavelength of emitted radiation is $\lambda$. If an electron jumps from $N$-shell to the $L$-shell, the wavelength of emitted radiation will be :
- 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:
