Explain the directing effects of the methyl group in toluene during Friedel-Crafts acylation.

Product Analysis:
Toluene has a methyl group ($\text{-CH}_3$) which is an activating group and an ortho/para-director in electrophilic aromatic substitution reactions. This means it increases the electron density of the aromatic ring, making it more reactive towards electrophiles, and directs the incoming electrophile to the ortho and para positions relative to the methyl group.

Therefore, Friedel-Crafts acylation of toluene will primarily yield a mixture of ortho- and para-substituted products. The para isomer is typically the major product due to reduced steric hindrance between the methyl group and the incoming acyl group.

For example, if acetyl chloride ($\text{CH}_3\text{COCl}$) is used as
