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.) H₂SeO₄ is a stronger acid than H₂SO₄ because Se is larger than S.

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

d.) H₃AsO₄ is a stronger acid than H₃PO₄ because As is larger than P.

e.) H₂S is a stronger acid than PH₃ because S is more electronegative than P.

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

Answer 1

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

b.) H₂SeO₄ is a stronger acid than H₂SO₄ because Se is larger than S.= True (Greater the bond length , stronger is the acid)

c.) HF is a stronger acid than H₂O because F is more electronegative than O.= True

d.) H₃AsO₄ is a stronger acid than H₃PO₄ because As is larger than P. = True (Greater the bond length , stronger is the acid)

e.) H₂S is a stronger acid than PH₃ because S is more electronegative than P. = False

f.) H₂SeO₄ is a stronger acid than HClO₄ because Se is larger than Cl.= True (Greater the bond length , stronger is the acid)
