Question: Which of the following compounds undergoes electrophilic substitution most readily?

Options:

Correct Answer: Toluene

Solution:

Toluene undergoes electrophilic substitution most readily due to the electron-donating effect of the methyl group, which activates the benzene ring.

Which of the following compounds undergoes electrophilic substitution most readily?

Which of the following compounds undergoes electrophilic substitution most readily?

Step 1: Understand what electrophilic substitution is. It is a reaction where an electrophile replaces a hydrogen atom in a benzene ring.
Step 2: Identify the compounds given in the question. Look for toluene and other possible compounds.
Step 3: Know that toluene is a benzene ring with a methyl group attached to it.
Step 4: Recognize that the methyl group is an electron-donating group. This means it helps to increase the electron density of the benzene ring.
Step 5: Understand that a higher electron density on the benzene ring makes it more reactive towards electrophiles.
Step 6: Compare toluene with other compounds. If they have groups that withdraw electrons, they will be less reactive than toluene.
Step 7: Conclude that toluene undergoes electrophilic substitution most readily because the methyl group activates the benzene ring.
