Question

Select all of the correct statements about the relative acid strengths of pairs of acids from the choices below.

A. HCl is a stronger acid than H₂S because Cl is more electronegative than S.

B. PH₃ is a stronger acid than H₂S because P is larger than S.

C. HBr is a stronger acid than H₂Se because Br is more electronegative than Se.

D. H₂Se is a stronger acid than HBr because Se is larger than Br.

E. HNO₃ is a stronger acid than HNO₂ because it has more oxygens surrounding the central N atom.

F. HBrO₃ is a stronger acid than HBrO₂ because it has more oxygens surrounding the central Br atom.
