Questions & Step-by-Step Solutions
Which of the following compounds is a strong activating group for 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: Know what activating groups are. Activating groups increase the reactivity of the aromatic ring towards electrophiles.
Step 3: Identify the -OH group (hydroxyl group). It is a functional group that consists of an oxygen atom bonded to a hydrogen atom.
Step 4: Learn how the -OH group affects the aromatic ring. The -OH group can donate electron density to the ring, making it more reactive.
Step 5: Conclude that since the -OH group donates electrons, it is classified as a strong activating group for electrophilic aromatic substitution.
