Questions & Step-by-Step Solutions

What is the effect of a -COOH group on the stability of a benzene ring?
  • Step 1: Understand what a benzene ring is. It is a stable structure made of six carbon atoms arranged in a circle, with alternating double bonds.
  • Step 2: Learn about functional groups. A -COOH group is called a carboxylic acid group and is known to attract electrons.
  • Step 3: Recognize that the -COOH group is an electron-withdrawing group. This means it pulls electrons away from the benzene ring.
  • Step 4: Realize that when electrons are pulled away from the benzene ring, it becomes less stable.
  • Step 5: Conclude that the presence of a -COOH group destabilizes the benzene ring due to its strong electron-withdrawing effect.
