Question

There are some arrangements of atomic orbitals which are given below :
[SEE DIAGRAM]
Then calculate the value of "$Q imes R - P$" where, P, Q and R are no. of arrangements which give bonding molecular orbitals (positive overlap), antibonding molecular orbitals (negative overlap) and non-bonding molecular orbitals (zero overlap) respectively.

Correct answer: 2

**SOLUTION:** (P) = (I), (III), (IV), (VII) (4)
(Q) = (II), (V), (IX) (3)
(R) = (VI), (VIII) (2)
THEN $Q \TIMES R - P = 3 \TIMES 2 - 4 = 2$
