Answer:

c and o

Explanation:

Carbon and Oxygen cannot react to form an ionic compound because the two elements are non-metals.

  • To form an ionic bond, a metal combines with a non-metal through electrostatic attraction of oppositely charged ions.
  • This leads the bond formation.
  • Carbon is a non-metal, with oxygen, they will prefer to form a covalent bond where they share their electrons

The pair of elements that could not react to form an ionic compound is C and O. Thus option B is correct.

Ionic compounds are formed by the electrostatic interaction of the metal atom with a non-metal. The ionic bonds are weaker bonds and are easily dissociated in the water.

The ionic compounds can be:

  • CO and Br are metal and nonmetal with different charges, and thus form the ionic compound.

  • C and O, both are non-metals, and thus will not form an ionic compound.

  • K and F, having K as metal and F as a nonmetal forming the ionic compound.

  • Ag and O, have a metal and a nonmetal and have been able to form an ionic compound.

The pair of elements that could not react to form an ionic compound is C and O. Thus option B is correct.
