Identify the correct statement from the statements given below.

Options

APhosphinic acid is a diprotic acid while phosphonic acid is a monoprotic acid.
BPhosphinic acid is a monoprotic acid while phosphonic acid is a diprotic acid.
CBoth are triprotic acids
DBoth are diprotic acids

Correct answer

B. Phosphinic acid is a monoprotic acid while phosphonic acid is a diprotic acid.

Step-by-step 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
