Questions & Step-by-Step Solutions
Which of the following is an example of a -I effect?
Correct Answer: -F group
Step 1: Understand what -I effect means. It refers to the electron-withdrawing effect of certain groups in a molecule.
Step 2: Identify the groups that exhibit -I effect. Common examples include halogens like -F (fluorine), -Cl (chlorine), -Br (bromine), and -I (iodine).
Step 3: Recognize that the -F group (fluorine) pulls electron density away from the rest of the molecule through sigma bonds.
Step 4: Conclude that since -F is an electron-withdrawing group, it is indeed an example of a -I effect.
