Question

1. what is the bond order of the carbon - oxygen bond in cof2?

a. 1.5
b. 2.5
c. 2
d. 3
e. 1

Explanation:

Step1: Draw Lewis structure

Carbon has 4 valence - electrons, oxygen has 6, and each fluorine has 7. In $COF_2$, carbon is the central atom. The Lewis structure has a double - bond between carbon and oxygen and single - bonds between carbon and each fluorine.

Step2: Determine bond order

The bond order of a bond is the number of bonding pairs of electrons between two atoms. A single bond has a bond order of 1, a double bond has a bond order of 2, and a triple bond has a bond order of 3. In the $C = O$ bond of $COF_2$, the bond order is 2.

Answer:

C. 2
