Which amine is most likely to undergo electrophilic aromatic substitution?
Step 1: Understand what electrophilic aromatic substitution (EAS) is. It is a reaction where an electrophile replaces a hydrogen atom on an aromatic ring.
Step 2: Identify the types of groups attached to the aromatic ring. These groups can either activate or deactivate the ring towards EAS.
Step 3: Recognize that amines (like aniline) have an amino group (-NH2) that can donate electrons to the aromatic ring.
Step 4: Know that the amino group is a strong activating group, which means it makes the aromatic ring more reactive towards electrophiles.
Step 5: Compare aniline with other amines. Aniline has the strongest activating effect due to its amino group.
Step 6: Conclude that aniline is the most likely amine to undergo electrophilic aromatic substitution because it enhances the reactivity of the aromatic ring.
