Which of the following groups is a weak -I effect group?

Which of the following groups is a weak -I effect group?

Correct Answer: Halogens

Step 1: Understand what -I effect means. The -I effect refers to the electron-withdrawing effect of certain groups in a molecule.
Step 2: Identify the groups that exhibit -I effect. Common groups include halogens (like F, Cl, Br, I) and others.
Step 3: Recognize that the strength of the -I effect varies among these groups. Some groups are stronger at pulling electrons than others.
Step 4: Focus on the halogens. They are a specific group where the -I effect decreases as you move down the group from fluorine to iodine.
Step 5: Conclude that iodine (I) has the weakest -I effect among the halogens, making it the weakest -I group.
