Draw the Lewis structure of CO molecule

Explanation

Step 1 :Count the total number of valence electrons of carbon and oxygen atoms. The outer (valence) shell congurations of carbon and oxygen atoms are `2s^(2)` `2p^(2)` and `2s^(2) 2p^(4)` respectively The valence electrons avilabe are `4 +6 =10`
Step 2 : The skeletal strucure of `CO` is written as `CO`
Step 3 : Draw a single bond(one shared electron pair) between `C` and `O` and complete the octet on `O` the remaining two electrons are the lone pair on `C`
`:C:overset(..)underset(..)(O):` or `:C-overset(..)underset(..)(O):`
This does not not complete the octel on carbon and hence we have to resort to multiple bonding (in this case a triple bond) between `C` and `O` atoms This satisfies the octet rule condition for both atoms
