Q81 / 180 · NEET 2016 (Phase 1) · Chemistry

Identify the correct statement from the statements given below.

A
Phosphinic acid is a diprotic acid while phosphonic acid is a monoprotic acid.
Correct answer
B
Phosphinic acid is a monoprotic acid while phosphonic acid is a diprotic acid.
C
Both are triprotic acids
D
Both are diprotic acids

Solution

Phosphinic acid is Hypophosphorous acid

H_{3} P O_{2}

which is Monobasic acid as only one

H

-atom is attaches to only one oxygen atom while in Phosphonic acid is phosphorous acid

H_{3} P O_{3}

which is Dibasic acid in which two

H

-atoms are attched to oxygen atom

Hence, the correct answer is option: 'B'.
