Consider an oxygen atom contained in a neutral molecule, like those in Model 1. Give the name for the electrons around the oxygen that are not involved in a covalent bond. What bond angle is formed when oxygen forms two single bonds? What shape is formed? Which functional groups in Model 1 are polar? When a carbon atom forms a double bond to an oxygen atom, it is called a carbonyl group. Which functional groups in Model 1 contain a carbonyl group?
