Question

The Lewis electron-dot diagrams of the HClO3 molecule and the HClO2molecule are shown above at the left and right, respectively.

Which of the following statements identifies the stronger acid and correctly identifies a factor that contributes to its being the stronger acid?

(A)HClO3(aq)is the stronger acid because its molecules experience stronger Londondispersion forces.

(B)HClO3(aq)is the stronger acid because the additional electronegative oxygen atom on the chlorine atom stabilizes the conjugate base.

(C)HClO2(aq)molecules experience weaker London dispersion forces. is the stronger acid because its

(D)HClO2(aq)is the stronger acid because the Acid Solution Volume of NaOH Added (mL) A40B75C115D200lone pairs of electrons on the chlorine atom stabilize the conjugate base.

Answer 1

Option (B) is correct

Step-by-step explanation:

Atom is the smallest existing particle of a chemical element.

`HClO_3` has three electronegative oxygen atoms and
`HClO_2` has two electronegative oxygen atoms

Therefore,

`HClO_3` (aq) is the stronger acid because the additional electronegative oxygen atom on the chlorine atom stabilizes the conjugate base.

Option (B) is correct.
