Question

if the bid order is 3 then it is paramegnetic of diamegnetic​

Answer 1

Answer:

Ifthe sum of number of electrons in a species are odd numbered they paramagnetic, if even numbered diamagnetic (exception O2,B2 - like species having 16 electrons, and 10 electrons species like B2 are paramagnetic due to presence of unpaired electrons in molecular orbitals according to molecular orbital theory). Bond order= 1/2(Nb- Na). Where Na is number of electrons in antibonding orbitals, Nb is number of electrons in bonding orbitals. If the bond order is integer, species is diamagnetic ( except 10 electron, 16 electron species).
