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) H2Se is a stronger acid than HBr because Se is larger than Br

c) H2O is a stronger acid than HF because O is larger than F.

d) H2SeO4 is a stronger acid than HClO4 because Se is larger than Cl.

e) HBrO4 is a stronger acid than H2SeO4 because Br is more electronegative than Se.

f) HBrO4 is a stronger acid than HIO4 because Br is more electronegative than I.

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

e) HBrO4 is a stronger acid than H2SeO4 because Br is more electronegative than Se.

f) HBrO4 is a stronger acid than HIO4 because Br is more electronegative than I.

The remaining options are incorrect.

b) H2Se is a stronger acid than HBr because Se is larger than Br

In this case HBr is tronger acid.

c) H2O is a stronger acid than HF because O is larger than F.

Here HF is stronger than H2O

d) H2SeO4 is a stronger acid than HClO4 because Se is larger than Cl.

Here also HClO4 is stronger than H2SeO4
