The next functional group under study is the "carbonyl" group, or double-bonded oxygen.  If it is on the end of the carbon chain it is an aldehyde, and if in the middle it is a ketone.  Read p.49-56.  Note that ketones are now named with the location number just before the -one ending, such as with pentan-2-one instead of 2-pentanone.
Homework:  Answer p.51-52 #1-5; p.56 #6-7; p.57 #1-4.
