Question

Which of the following parent oxy acid does not have its hypo acid-H-2-SO-2-HNO-2-H-3-PO-3-HClO-3-

Toppr Admin · Accepted Answer

Hypo acid means the main element have lower oxidation state than the present acid-Here-xA0-HClO-HClO2 are Hypo acid-xA0-HClO3-xA0- -xA0- -xA0- -xA0- -xA0-xA0-H3PO2 is hypo acid of-xA0-H3PO3-xA0- -xA0- -xA0- -xA0- -xA0- HNO is hypo acid of-xA0-HNO2But-xA0-H2SO2 doesn-apos-t have hypo acidAns - Option A-

Which of the following parent oxy acid does not have its hypo acid?H2SO2HNO2H3PO3HClO3

Hypo acid means the main element have lower oxidation state than the present acid.Here, HClO,HClO2 are Hypo acid HClO3 H3PO2 is hypo acid of H3PO3 HNO is hypo acid of HNO2But H2SO2 doesn't have hypo acidAns :- Option A.

Which of the following parent oxy acid does not have its hypo acid?
$H_{2} S O_{2}$
$H N O_{2}$
$H_{3} P O_{3}$
$H C l O_{3}$

Hypo acid means the main element have lower oxidation state than the present acid.
Here, $H C l O, {H C l O}_{2}$ are Hypo acid ${H C l O}_{3}$
$H_{3} {P O}_{2}$ is hypo acid of $H_{3} {P O}_{3}$
$H N O$ is hypo acid of ${H N O}_{2}$
But $H_{2} {S O}_{2}$ doesn't have hypo acid
Ans :- Option A.
