CBSE Class 11-science Answered
Using Molecular Orbital theory, compare the bond enthalpy and bond length of CN and CN- species.
Asked by Topperlearning User | 13 Jun, 2016, 02:45: PM
Expert Answer
Number of electron in CN = 6+7=13
MO configuration of CN
B.O = 
[7-2] = 2.5
[7-2] = 2.5MO configuration of CN-
BO = (8-2) = 3
(8-2) = 3Higher the bond order greater is the bond energy and shorter is the bond length. Hence bond enthalpy of CN- is greater than CN and bond length of CN- is shorter than the bond length of CN.
