Q: What is the effect of a -CF3 group on the stability of a benzene ring?
Solution: -CF3 is a strong electron-withdrawing group, which destabilizes the benzene ring.
Steps: 5
Step 1: Understand what a benzene ring is. It is a stable structure made of six carbon atoms connected in a ring, with alternating double bonds.
Step 2: Learn about functional groups. A -CF3 group is a chemical group that consists of one carbon atom bonded to three fluorine atoms.
Step 3: Know that -CF3 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. Stability in benzene comes from its ability to share electrons evenly.
Step 5: Conclude that the presence of a -CF3 group destabilizes the benzene ring because it reduces the electron density.
