Question

The hybridization of carbon and oxygen in $CO$ are respectively:

• A. $sp,sp$
• B. ${sp}^2,sp$
• C. ${sp}^2,{sp}^2$
• D. $sp,{sp}^2$

Answer 1

The correct option is A $sp,sp$

The hybridization of carbon and oxygen in $CO$ are $sp,sp$ respectively. $CO$ has a triple bond between the atoms, with one unshared pair of electrons each on $C$ and $O$. The carbon atom has a negative charge, and the oxygen atom has a positive charge. So hybridization on both atoms is $sp$.
