An amine $(\text{X})$ is prepared by ammonolysis of benzyl chloride. On adding $p$-toluenesulphonyl chloride to it, the solution remains clear.Molar mass of the amine $(\text{X})$ formed is _____ $\text{g mol}^{-1}$.(Given molar mass in $\text{g mol}^{-1}$: $\text{C} = 12, \, \text{H} = 1, \, \text{O} = 16, \, \text{N} = 14$)

X of enthanamine was subjected to reaction with $NaNO_2/HCl$ followed by hydrolysis to liberate $N_2$ and HCl. The HCl generated was completely neutralised by 0.2 moles of NaOH. X is ____ g.

Number of amine compounds from the following giving solids which are soluble in NaOH upon reaction with Hinsberg's reagent is _____.

Given below are two statements:
Statement (I) : All the following compounds react with p-toluenesulfonyl chloride.
$C_6H_5NH_2 \quad (C_6H_5)_2NH \quad (C_6H_5)_3N$
Statement (II) : Their products in the above reaction are soluble in aqueous NaOH.
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 ______.

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:

The azo-dye (Y) formed in the following reactions is: Sulphanilic acid + NaNO$_2$ + CH$_3$COOH → X

Identify A and B in the following reaction sequence.

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.
