Question

Consider the following oxyanions :
PO4^3-, P2O4^4-, SO4^2-, MnO4^-, CrO4^2-, S2O5^2-, S2O7^2-
and find the value of R + Q - P
Where P = Number of oxy anions having three equivalent X—O bonds per central atom
Q = Number of oxy anions having two equivalent X—O bonds per central atom
R = Number of oxy anions having four equivalent X—O bonds per central atom

Prashant Kotian · Accepted Answer

Correct answer: 3 / P = 3, Q = 2, R = 4. R + Q - P = 4 + 2 - 3 = 3
