All right, problem 80.
00:03
Okay, we are asked to define the structural difference between an aldos and a ketos.
00:10
Okay, so right off the bat, we could see that these are sugars, okay, because of the suffix ose.
00:18
So that's a suffix we use for sugars.
00:23
And then what i have down here are two different structures of sugars.
00:27
And this is not included in the problem.
00:28
This is actually from a previous problem.
00:31
In the same chapter but i thought there would be there would be good examples for this problem okay so so we got the ose which stands for sugar and then we got al for aldose and then key for ketos okay so aldose from the prefix ald that means we got alde okay means we got aldehyde and then key for ketos means we have a ketone so that gives us our structural difference right an aldeose would have an aldehyde and a kitos will have a ketone and so we look at our sugars here we look at part a and we see that does it have does it have a ketone no our carbonal group here is at the end and it's attached to a carbon and then attached to a carbon and then attached to a hydrogen, which means we have an aldehyde...
