in a pyriphosphoric acid number of sigma and Pi bonds
Hello,
The total number of sigma bonds in pyrophosphoric acid are 12 and Pi bonds in pyrophosphoric acid are 2. The two double bonds contributes 2 sigma and 2 d Pi−p Pi.
There are 4 O-H groups = 4 sigma bonds
There are 6 P-O type of bonds.
Total no. of sigma bonds = 2+ 4+ 6 =12
Total no. of d Pi−p Pi bonds= 2
So There are 12 sigma bonds and 2 Pi bonds
