Which of the following acids are stronger than acetic acid in water?
ACHX3CHX2COOH
BClCHX2COOH
C(CHX3)X3CCOOH
DHCOOH
Answer: B, D
ClCHX2COOH has the -I chlorine, and HCOOH has no +I alkyl group, so both anions are better stabilised than acetate. (CHX3)X3CCOOH and CHX3CHX2COOH have bigger +I alkyl groups and are weaker.
