Chemistry Question on Alcohols, Phenols And Ethers
Explain how does the –OH group attached to a carbon of benzene ring activate it towards electrophilic substitution?
Answer
The -OH group is an electron-donating group. Thus, it increases the electron density in the benzene ring as shown in the given resonance structure of phenol. As a result, the benzene ring is activated towards electrophilic substitution.
