Cycloserine is an antibiotic isolated from the microbe Streptomyces orchidaceous. It is used in conjunction with other drugs for the treatment of tuberculosis.
(d) How many sp-hybridized carbon atoms are present in this structure?
Alright guys. So, for this question, let's first draw our molecule to reference it, and there's going to be an oxygen, a nitrogen, a carbonyl, right? And then an NH2 coming off and of course there's a hydrogen here. Now, for this molecule we're looking for only sp hybridized carbon atoms. Now, for sp you should be familiar about it because it's something that you should see more along the line, it's a triple bond, right? Because a carbon has 2 things that it's attached to, so for sp be aware that commonly this is triple bond, that's what we're going to see in hybridized carbon but it's not limited to triple bonds, right? So, notice that here this one's going to be what? sp 3 hybridized be cause it has two hydrogens, this one is going to be sp3 hybridized as well because there;s a hydrogen coming off here and then finally this carbon right here, what do you guys think? Well, that one is gonna be just sp2 hybridized because it has, it's connected to an oxygen, a nitrogen and a carbon, so that's where we get sp2, so you see sp2 hybridized carbon atoms. Now, right, there's no hybridized carbon atoms, so we can say, none, right? how many is there? there's none here in this structure, we only have sp2 and sp3. Alright guys, so hopefully that made sense.
