Final answer:
To draw the Lewis structures of OF2 and CO2, you need to determine the number of valence electrons for each atom. For OF2, oxygen will form a double bond with one fluorine atom and the other fluorine atom will have a lone pair. For CO2, carbon is double bonded to both oxygen atoms.
Step-by-step explanation:
To draw the Lewis structures of OF2 and CO2, we need to determine the number of valence electrons for each atom. Oxygen (O) has 6 valence electrons, while fluorine (F) has 7 and carbon (C) has 4.
For OF2, we have oxygen (O) bonded to fluorine (F). Oxygen will form a double bond with one of the fluorine atoms, and the other fluorine atom will have a lone pair. The structure is O=F-F.
For CO2, we have carbon (C) double bonded to both oxygen (O) atoms. Each oxygen atom will have two lone pairs. The structure is O=C=O.
