What is the effect of the -I effect on acidity?
Correct Answer: The -I effect increases acidity.
- Step 1: Understand that acidity refers to how easily a substance can donate a proton (H+).
- Step 2: Know that when an acid donates a proton, it forms a conjugate base, which is the remaining part of the acid.
- Step 3: The -I effect (inductive effect) occurs when electronegative atoms or groups pull electron density away from the rest of the molecule.
- Step 4: When the -I effect is present, it helps to stabilize the negative charge on the conjugate base after the acid donates a proton.
- Step 5: A more stable conjugate base means that the original acid is more likely to donate its proton, which increases acidity.
