Answer 1

The correct option in the following

A) Phosphoric acid has two P-H bonds.

• It is not correct.

B) Orthophosphoric acid has two P=O bonds.

• It is not correct.

C) Hyo Phosphoric acid has no P-O-P bond.

• It is correct.

• It is not correct.

Answer 2

$\sf{\blue{\underline{\underline{\pink{GIVEN:-}}}}}$

• a) Phosphonic acid has two P-H bonds .

• b) Orthophosphoric acid has two P=O bonds .

• c) Hypo phosphoric acid has no P-O-P bond .

• d) Pyrophosphoric acid has two P-OH bonds .

$\sf{\blue{\underline{\underline{\pink{TO\: FIND:-}}}}}$

• Select the correct option from the above given options .

$\sf{\blue{\underline{\underline{\pink{SOLUTION:-}}}}}$

✍️ See the attachment structures .

a] PHOSPHONIC ACID :-

• Formula :- $\bf\pink{H_3\:O_3\:P}$

☃️ Hence, from the above structure we can found that Phosphonic acid carry only one P-H bond .

☃️ But according to the question, Phosphonic acid has two P-H bonds, which is a wrong statement .

b] ORTHO PHOSPHORIC ACID :-

• Formula :- $\bf\red{H_3\:P\:O_4}$

☃️ Hence, from the above structure we can found that Orthophosphoric acid carry only one P=O bond .

☃️ But according to the question, Orthophosphoric acid has two P=O bonds, which is a wrong statement .

c] HYPO PHOSPHORIC ACID :-

• Formula :- $\bf\blue{H_4\:P_2\:O_6}$

☃️ Hence, from the above structure we can found that Hypophosphoric acid carry no P-O-P bond .

☃️ But according to the question, Hypophosphoric acid has no P-O-P bond, which is a correct statement .

d] PYRO PHOSPHORIC ACID :-

• Formula :- $\bf\purple{H_4\:P_2\:O_7}$

☃️ Hence, from the above structure we can found that Pyrophosphoric acid carries four P-OH bonds .

☃️ But according to the question, Pyrophosphoric acid has two P-OH bonds, which is a wrong statement .
