Question

How many bonds are present in cyclic metaphosphoric acid?

Answer 1

Cyclic metaphosphoric acid(${\mathrm{H}}_3{\mathrm{P}}_3{\mathrm{O}}_9$):

• Metaphosphoric acid is a corrosive, inorganic, cyclic polyphosphate formed from bonded phosphoric acid units.
• The total number of P-O-P bonds is 3.
• The total number of P-O-H bonds is 3.
• The total number of P=O bonds is 3.

Hence, there are 12 single bonds and 3 double bonds in cyclic metaphosphoric acid.
