Place the following in order of increasing acid strength.

hbro2 hbro3 hbro hbro4

a) hbro2 < hbro4 < hbro < hbro3
b) hbro < hbro2 < hbro3 < hbro4
c) hbro2 < hbro3 < hbro4 < hbro
d) hbro4 < hbro2 < hbro3 < hbro
e) hbro < hbro4 < hbro3 < hbro2

Option (B) is the correct answer.

Explanation:

As oxygen atom is highly electronegative than hydrogen atom. So, when there will be presence of more number of oxygen atoms in a compound then it means that compound can easily lose a hydrogen ion.

This is because more oxygen atoms will have more electron pull of shared electrons. Thus, hydrogen atom can be removed easily when dissolved in an aqueous solution.

Thus, we can conclude that order of increasing acid strength is as follows.

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.
