Given below are two statements:
Statement I : The 
group in aniline is ortho and para directing and a powerful activating group.
Statement II : Aniline does not undergo Friedel - Crafts reaction (alkylation and acylation).
In the light of the above statements, choose the most appropriate answer from the options given below :
is incorrect but Statement II is correct. Text Solution
Verified by ExpertsC
: The groups which direct the incoming group to ortho and para positions are called ortho and
para directing groups.
Let us discuss the directive influence of 
group. Aniline is resonance hybrid of following structures.
It is clear from the above resonating structures that the electron density is more on 
and 
positions. Hence, the substitution takes place mainly at these positions. Aniline does not undergo Friedel-Crafts reaction (alkylation and acylation) due to salt formation with aluminium chloride, the Lewis acid, which is used as a catalyst. Due to this nitrogen, of aniline acquires positive charge and hence acts as a strong deactivating group.
