INCORRECT!
- Type of reaction
This is a Friedel-Crafts acylation, which is a type of electrophilic aromatic substitution that occurs on aromatic rings that are not strongly deactivated.
- Position of attack
The methyl group directs the attack ortho/para, so this product (from para attack) is substituted at the correct position.
- Position of C=O
