What is friedel craft reaction not probit in presence of moisture? |
|
Answer» 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. |
