A mixture containing the following four compounds is extracted with 1M HCl. The compound that goes to aqueous layer is :
Show Hint
- (I)
- (II)
- (III)
- (IV)
The Correct Option is B
Solution and Explanation
Only the amine (II) is basic enough to be protonated by 1M HCl: \(\mathrm{R_2NH + HCl \rightarrow R_2NH_2^+Cl^-}\). The ammonium salt is ionic and dissolves in the aqueous layer. The sulphide, ether and ketone stay in the organic layer.
Answer: (2) (II)

Top JEE Main Amines Questions
- Statement-I : Aniline on reaction with concentrated \(H_2SO_4\) at 475 K gives p-amino benzene sulphonic acid. This gives blood red colour with Lassaigne’s test.
Statement-II : Aniline forms a salt with anhydrus \(AlCl_3\) in Friedel Craft’s reaction. - Identify A and B in the following reaction sequence.
- The azo-dye (Y) formed in the following reactions is: Sulphanilic acid + NaNO$_2$ + CH$_3$COOH → X
- Given below are two statements:
Statement I: Aniline reacts with con. \( H_2SO_4 \) followed by heating at 453–473 K gives p-aminobenzene sulphonic acid, which gives blood red colour in the 'Lassaigne's test'.
Statement II: In Friedel-Craft's alkylation and acylation reactions, aniline forms salt with the \( AlCl_3 \) catalyst. Due to this, nitrogen of aniline acquires a positive charge and acts as a deactivating group.
In the light of the above statements, choose the correct answer from the options given below: - A compound (\( x \)) with molar mass \( 108 \, \text{g mol}^{-1} \) undergoes acetylation to give a product with molar mass \( 192 \, \text{g mol}^{-1} \). The number of amino groups in the compound (\( x \)) is ______.

- 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:
