Question

The no. of P – O – P bond (s) in cyclic metaphosphoric acid is (are):
A. 0
B. 2
C. 3
D. 4

Answer 1

Hint- To find the number of bonds in cyclic metaphosphoric acid, refer to the structure of the given acid and then find the number of P – O – P bonds.

Complete answer:
We have been given to find the number of P – O – P bonds in the cyclic metaphosphoric acid.
So, let us first draw the structure of the given acid.
Refer the figure below to know the structure-

The figure shows the structure of cyclic meta phosphoric acid.
Now, as we can see that the above structure has P – O – P bond, P=O bond and P – O – H bonds.
So, if we count then the number of P – O – P bonds are three (See in the figure)
Hence, the number of P – O – P bonds in the structure of cyclic metaphosphoric acid is three.

Therefore, the correct option is C.

Note – Whenever it is asked to tell the number of bonds of any acid or compound then always first draw the structure of that compound and then as we can see the given structure has 3 P – O – P bonds, 3 P = O bonds and 3 P – O – H bonds.
