Q 1 :    

The products A and B formed in the following reaction scheme are respectively                          [2024]

Q 2 :    

The azo-dye (Y) formed in the following reactions is

$\text{Sulphanilic acid}+{\text{NaNO}}_2+{\text{CH}}_3\text{COOH}\to X\mathit{.}$                            [2024]

Q 3 :    

Given below are two statements:                                                  [2024]

Statement I: Aniline reacts with con. ${\text{H}}_2{\text{SO}}_4$, 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 ${\text{AlCl}}_3$ 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:

• Both statement I and statement II are true

   

• Both statement I and statement II are false

   

• Statement I is true but statement II is false

   

• Statement I is false but statement II is true
