what is friedel craft reaction not probit in presence of moisture?
Answers
Answer:
FriedelCrafts alkylation involves alkylation of an aromatic ring with an alkyl halide using a strong Lewis acid catalyst. With anhydrous ferric chloride as a catalyst, the alkyl group attaches at the former site of the chloride ion.
Due to strong -I & -M effect of $$-NO_2$$ & $$-N^+Me_3$$ group, the electron density of benzene decreases and electrophilic substitution become difficult.
In case of aniline, it acts as a base and reacts with Lewis acid; and formation of cation become difficult and reaction doesn't happen.
Answer:
The Friedel–Crafts reactions are a set of reactions developed by Charles Friedel and James Crafts in 1877 to attach substituents to an aromatic ring.[1] Friedel–Crafts reactions are of two main types: alkylation reactions and acylation reactions. Both proceed by electrophilic aromatic substitution
