The orbital energy ladder (molecular orbital energy level diagram) for NO and NO+ is given below.
1. a). Populate each with the appropriate number of electrons.
NO
_________ sp(z)*
_________ _________ px,y*
_________ _________ px,y
_________ sp(z)
_________ ss*
_________ ss
NO+
_________ sp(z)*
_________ _________ px,y*
_________ _________ px,y
_________ sp(z)
_________ ss*
_________ ss
b). Calculate the bond order.
c). Which molecule is more stable?
d). State any unsual observation you might notice about NO.

____2_____ ss
b) B.O. = 1/2[bonding- antibionding]
NO B.O.= 1/2[10-5] = 2.5
NO+ = 1/2[10-4] = 3
c) NO+ is more stable
D) NO is para magnatic molecule or itis a odd electron molecule
