Question

2 chloropropanoic acid is more acidic than 3 chloro propanoic acid why

Answer 1

In2-chloropropanoic acid Cl is at 2nd position of numbering in chain and therefore,
the -inductive effect is distance dependent.
The distance to -COOH group for Cl is less than in 3-chloropropanoic acid and hence it has more -I effct which makes it more stable and stronger.

Answer 2

2- chloropropanoic acid is more acidic than 3-chloripropanoic acids because of the pk value of 2-chloropropanoic acid less that's why it is more acidic than 3-chloropropanoic acid.

• If the Pk value of any acid is less, the power of acid will be more, so the acid will be strong and more stable.

• 2-chloripropanlic acid is a colorless liquid and in this Cl is at 2nd position of numbering in the chain.

• The chemical formula of 2- chloropropanoic acid is CH3CHCLCO2H.

• This acid is a neurotoxin, more acidic in nature.
