Which of the following is isoelectronic?
Multiple Choice Options
- A
- B
- C
- D
Step-by-Step Verified Solution
In CO, the number of electrons
_ 6 + 8 = 14 [ Z of C = 6 and O = 8]
Electronic configuration of molecular orbital of CO :
( _ 1 s ) 2 ( _ _ 1 s ) 2 ( _ 2 s ) 2 ( _ _ 2 s ) 2 ( � 2 p x ) 2 ( � 2 p y ) 2 ( � 2 p z ) 2
CN - also get (6 + 7 + 1) 14 electrons and the configuration is similar to that CO.
So, CN and CO is isoelectronic.
