Ketone structure #2.46

Postby Isha Bagga 3J » Thu Mar 05, 2015 8:21 pm

For number 46 in chapter 2, it asks to name all the functional groups in the aspartame molecule. I thought there were some ketones in there, with the double bonded oxygen, but I think I might be confused on what a ketone functional group is because the answer didn't have ketone. If anyone could explain what the double bonded oxygens are there for, I would appreciate it!

There are a wide assortment of different functional groups which all involve carbonyl (C=O). It is only called ketone when both sides of the carbonyl are alkyl groups. ... groups.jpg

Notice that aspartame has 3 carbonyls, but by looking what's near the C=O, you can tell that you have 1) carboxylic acid, 2) amide, 3) ester

I made a video explaining how to distinguish certain c=o structures. The file was too large so I had to upload it to YouTube. The link is below.
