Calculate the number of bonding electron pairs and nonbonding electron pairs around the central atom of OF2

To calculate the number of bonding and nonbonding electron pairs around the central atom of OF2, we first need to understand the molecule's structure and the valence electrons of each atom.

1. Identify the central atom: In OF2, Oxygen (O) is the central atom.

2. Count the valence electrons: Oxygen has 6 valence electrons. Each Fluorine (F) atom has 7 valence electrons, and since there are two Fluorine atoms, we have a total of 14 valence electrons from Fluorine. So, the total number of valence electrons in OF2 is 6 (from O) + 14 (from 2F) = 20 electrons.

3. Determine the number of bonding electron pairs: Each bond between Oxygen and Fluorine consists of 2 electrons, and since there are two O-F bonds, there are 4 electrons involved in bonding. Therefore, there are 2 bonding pairs (4 electrons/2).

4. Determine the number of nonbonding electron pairs: The remaining electrons that are not involved in bonding are considered nonbonding. We have 20 total valence electrons - 4 electrons in bonds = 16 nonbonding electrons. Since a pair of electrons is 2, we have 8 nonbonding pairs (16 electrons/2).

So, in OF2, there are 2 bonding electron pairs and 8 nonbonding electron pairs around the central Oxygen atom.
