Question

Which of the following is the strongest acid, and which is thestrongest base? a. CH3COOH b. ClCH2COOH c. Cl2CHCOOH d. Cl3CCOOH e. BrCH2COOH Which of the following is the strongest acid, and which is thestrongest base? a. CH3COOH b. ClCH2COOH c. Cl2CHCOOH d. Cl3CCOOH e. BrCH2COOH

Explanation / Answer

d) is the strongest acid When an acid deprotonates, it forms an anion HA => H+ + A- A- is more stabilized when it has electronegative atoms (Cl-) thatcan stabilize the excess charge. D) has three Cl, so it is moststabilized a) is the strongest base, because it has only H's ,whereas theothers have electronegative substituents (halogens like Cl and Br).Being the weakest acid, a), thus is the strongest base
