ecoli Posted October 21, 2005 Share Posted October 21, 2005 Why does NO+ have a triple bond? The formal charges would be the same with 1 bond and two lone pairs on each atom, so wouldn't it be just as stable? Link to comment Share on other sites More sharing options...
budullewraagh Posted October 21, 2005 Share Posted October 21, 2005 but then the octet rule wouldn't be satisfied. N-O nitrogen would have 2 lone pairs and the bond, so effectively 6 electrons. oxygen would have effectively 7 electrons. Link to comment Share on other sites More sharing options...
ecoli Posted October 21, 2005 Author Share Posted October 21, 2005 oh, right... that makes perfect sense. sorry for that question, I really should be seeing these things for myself. Link to comment Share on other sites More sharing options...
ajw2255 Posted October 21, 2005 Share Posted October 21, 2005 The best way to do it is with molecular orbital thory, if u look at O and N+ O has 2 electrons in 2s and 4 in 2p, and N+ has 2 is 2s and 2 in 2p. When the orbitals combine the s orbitals combine to form an antibonding and binding orbitals, so cancel out. The total 6 p electrons combine to form 3 bonding orbitals, with the 3 antibonding orbitals left empty. Gives a bond order of 3, --> triple bond.
