HBr HI HCl HF
List the above hydrogen halides in order from strongest acid to weakest acid.
Homework Answers
Acidity increases in the order: HF,HCl,HBr,HI
HF is the weakest acid as the polarising ability of fluorine is the highest and H-F bond is very strong.
As we move down the halogen group ,atomic size increases so H-X bond length increases and bond breaking energy becomes less,acidity increases(where X is any halogen)
