Q. A simplified application of $MO$ theory to the hypothetical ‘molecule’ $OF$ would give its bond order as:x

Chemical Bonding and Molecular Structure

Solution:

OF is derivative of $O_2$ and isoelectronic with $O_2^-$.
So $(\sigma 1s)^2 (\sigma^* 1s)^2 (\sigma 2s )^2 (\sigma^*2s)^2 (\sigma2p_z)^2 (\pi2p_x^2 = \pi 2 p^2_y) (\pi^*2p^2_x = \pi^*2p_y^1)$
The bond order of OF $1/2(10 - 7) = 1.5$.
