Answer» Correct Answer - A MO electronic configuration of `F_(2)` molecule is `F_(2)=sigma1s^(2),sigma^(**)1s^(2),sigma2s^(2),sigma^(**)2s^(2),sigma2p_(x)^(2).` `pi 2 p_(y)^(2)=pi 2p_(z)^(2), pi^(**) 2p_(y)^(2)=pi^(**)2p_(z)^(2)` Bond order `=(N_(b)-N_(a))/2` Where, `N_(b)`=Number of electrons in bonding molecular orbitals `N_(a)`=Number of electrons in antibonding molecular orbitals `=(8-6)/2=1` |
