The true statement for the acids of phosphorus, 'H3PO2, H3PO3 and H3PO4 ' is

A

their acidic nature is : `H_3PO_4 lt H_3PO_3 lt H_3PO_2`

B

all of them are reducing in nature

C

all of them are tribasic acids .

D

the geometry is tetrahedral in all the three

Text Solution

Verified by Experts

The correct Answer is:
D
The correct order is : `H_3PO_4 gt H_3PO_3 gt H_3PO_2`
Acids with contain P-H bonds have behave as reducing agents. `H_3PO_4` does not contain P-H bond
`H_3PO_4` : Tribasic `H_3PO_3` : Dibasic `H_3PO_2`: Monobasic
