What will be the bond order of the species with electronic configuration `1s^(2) 2s^(2) 2p^(5)`?A. OneB. TwoC. ThreeD. Zero

Answer» Correct Answer - A
Electronic configuration of atom ` : 1s^(2) 2s^(2) 2p^(5) ` M.O. configuration:
`(sigma 1s^(2))(sigma^(**)1s^(2))(sigma2s^(2)) (sigma^(**)2s^(2))(sigma2p_(z)^(2))(pi 2p_(x)^(2) = pi 2p_(y)^(2))(pi^(**)2p_(x)^(2)=pi^(**)2p_(y)^(2))`
B.O. ` = 1/2 xx (10 - 8) = 1`
