Hi, everyone. Welcome back. Our next question says, what is the line structure of the following compound? Does it contain an aldehyde functional group or a ketone functional group? So we have the starter line structure but our functional group is indicated just by letter symbols. So we have a five carbon ring with two double bonds and then one substituent. And if we label our substituent as being attached to carbon number one, our double bonds are on from carbon two to carbon three and then carbon four to carbon five. So the letter group that our functional group is indicated by is conh two. So what is this functional group? Well, this would be we have an attachment, we have a carbon, you would see a double bond to the oxygen. So a carbonyl group there and then attached to the carbon, you're going to see the nitrogen with two hydrogens. So we do have a carbon group as we do in aldehydes and ketones, but it is neither an aldehyde nor a ketone. It is an amid since it has that NH two group that gives it fundamentally different properties than either aldehydes or ketones. Let's recall that an aldehyde is in the form of R bond into ac with that double bond to nose. So it does have that carbonel group. But then just a hydrogen attached while a ketone has an R C double bond dose. Again, the carbonel group is similar to all three, but then a second R prime group attached to the carbon. So because the nitrogen attached to that carbon group gives it fundamentally different chemical properties. It gets its own name. So it's neither aldehyde nor ketone. But amid. So the last step we need, we have the name of what it is. We know it's neither of those two. We just need to give it the rest of its line structure. So we draw the ring again, five carbon ring with those double bonds on either side from carbon 2 to 3, from 4 to 5. And then on carbon one, I attach, I have a carbon here. So just make that a corner, I have a line segment and then a corner to indicate my carbon, but my carbon has a double bond to oxygen. So coming off of that carbon, we don't indicate specifically the carbon and aligned structure. So we just coming off the corner, we have the double bond to an oxygen recall that we do indicate other atoms besides carbon. And then, so it has a double bond to oxygen and then it also has a single bond. So another line segment going to our nitrogen. And then the nitrogen, we can just write as NH two, we do indicate hydrogens on atoms other than carbon. So we don't indicate any hydrogens on our ring, but we do indicate the hydrogens on the amid group. So there is our line structure showing our amid group which is neither an aldehyde nor a ketone despite having that carbonel group in common. See you in the next video.
