What IS bond order of CO molecule?

$\huge\orange{\boxed{\bold{❃ANSWER❃}}}$

CO comes in that group which has dative bonding and so students get confused so they get confused. The bond order of CO is 3 as oxygen shares two of its electrons with carbon and makes a dative bond filling it's shell. You can also simply prove it by molecular orbital theory.

Answer 2

Answer:

Species CO (14), contain bonding electrons=10 and antibonding electrons =4. Bond order =2Nb−Na=210−4=3.
