WebThe fill order for Ne is as follows: σ2s σ2s σ2p π2p π2p σ*2p What is the bond order of Ne2+ according to molecular orbital theory? 0.5 Which statement for NH3 and NF3 is false? Electronegativities: N = 3.0, H = 2.1, F = 4.0. The bond angles in NF3 are smaller than those in NH3. Both are sp3 hybridized at nitrogen. WebBond order is defined as one-half the difference between the number of electrons present in the bonding and the antibonding orbitals. The mathematical formula is as follows, Bond order (B.O.) = 1 2 (number of electrons in the bonding orbitals) - (number of electrons in the antibonding orbitals) Bond order of NO
