Answer:
A. CO
Explanation:
This is the answer I believe based on that it has the least amount of elements leading me to think that it would have the least ionic character.
The compound that contains a bond with the least ionic character is CO.
Ionic bonding involves transfer of valency electrons. Usually from a metal to a non metal.
The ionic character or nature of a bond is determined by the relative
electronegativity of the atoms involved.
So, the bigger the difference between the electronegativity of two atoms, the more likely it is to be ionic.
This simply implies that if the electronegativity differences of the atoms
involved are smaller, the ionic character will be small.
Therefore, the compound that contain a bond with the least ionic character is CO.
The difference in negativity of the carbon and oxygen atoms are small, this is
why the compound CO among the options possess the least ionic character.
