Q. The $fHOMO$ in CO is
A) $\pi$- bonding
B) $\pi$-antibonding
C) $\sigma$-antibonding
D) $\sigma$- bonding
Explanation
(d)
HOMO, means highest occupied molecular orbital and in CO (14 electron ion ),$\sigma$ bonding molecular orbital in HOMO
$CO = \sigma 1s^{2},\sigma^{*}1s^{2},\sigma 2s^{2},\sigma^{*}2s^{2},\pi 2p_{x}^{2} = \pi 2p_{y}^{2},\sigma 2p_{\mathcal{z}}^{2}$
