MCQ
In Friedal-Crafts acylation, besides $AlC{l_3}$, the other reactants are
- A
- ✓
- C
- D
✓
Answer
Correct option: B.
b
(b)In friedal craft acylation, aromatic compounds such as benzene, phenol etc. undergo acylation with $C{H_3}COCl$ in the presence of anhydrous $AlC{l_3}$ and gives ortho and para derivatives. Intermediate is $C{H_3}{C^ + } = O$ (acylium ion) of this reaction
In fact denotes friedel craft alkylation.
