In the nitration of toluene, which position is predominantly substituted?

In the nitration of toluene, which position is predominantly substituted?

Step 1: Understand that toluene is a benzene ring with a methyl group (CH3) attached.
Step 2: Know that nitration involves adding a nitro group (NO2) to the benzene ring.
Step 3: Identify the possible positions for substitution: ortho (next to the methyl group) and para (across from the methyl group).
Step 4: Recognize that the ortho position is hindered by the size of the methyl group, making it less favorable for substitution.
Step 5: Conclude that the para position is more favorable for substitution because it has less steric hindrance.
