The molecule below contains both an aldehyde and a ketone functional group. Select only the carbonyl carbon atom of the aldehyde functional group. Identify the carbon atom by selecting the atom and assigning it a map number of 1. To do this, right-click on an atom and choose Atom Properties. (Mac users: Use an equivalent for right-clicking.) Then, clear the check mark to enable the Map field before entering a value.
