Given below are two statements:
Statement I: Aniline reacts with con. , followed by heating at gives 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 deactivating group.
In the light of the above statements, choose the correct answer from the options given below:
Statement I: Aniline reacts with con. , followed by heating at gives 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 deactivating group.
In the light of the above statements, choose the correct answer from the options given below:
View answer and explanation
Correct option: C
Both statement I and statement II are true
The correct answer is C (Both statement I and statement II are true) because aniline does form p-aminobenzene sulfonic acid and gives a positive Lassaigne's test, and it also forms a salt with AlCl3, deactivating the ring.
