The products A and B formed in the following reaction scheme are respectively [2024]
(3)
The azo-dye (Y) formed in the following reactions is
[2024]
(1)
Given below are two statements: [2024]
Statement I: Aniline reacts with con. , 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 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
(1)
Statement (I)
In sulphanilic acid, nitrogen and sulphur both are present. So, in sodium fusion extract of sulphanilic acid, sodium thiocyanate is formed.
Sodium thiocyanate
Sodium thiocyanate gives blood-red colour with in Lassaigne’s test.
Blood red
Statement (II) : Aniline does not give Friedel-Craft’s alkylation and acylation reaction because aniline forms salt with (Lewis acid catalyst in the reaction). Due to this, nitrogen of aniline acquires a positive charge and hence acts as a strong deactivating group for further reaction.
Major product of the following reaction is [2024]
