Draw the condensed structural formula for each of the following alkyl groups:

(b) methyl

Accepted Answer

Welcome back, everyone provide the condensed formula for the ethel group. For this problem, we want to recall alkyl groups and their names. So first of all, whenever we start learning alkyl groups, we always begin with the methyl group, which is the simplest group, right? Essentially it is CH three, it only has one carbon bonded to three hydrogen atoms. Now methyl is followed by ethyl, which now contains two carbon atoms. So basically, we have two carbon atoms and every carbon will have a specific number of hygen. Now the carbon atom on the right will have three hygen based on the valency of carbon and the carbon atom at the beginning or based on the first carbon, it is going to have two hydrogen atoms. So ch two, right? And we are going to have some sort of bonding which is also followed by prophyl beetle and so on. Now we prop group will have three carbon atoms in general, we can just say that there would be C three H seven. So basically we can get the number of hygen by multiplying the number of carbon atoms by two and adding one. And this will essentially give us the general formula of any alkyl substituent. And in this case, while we are interested in the ethyl group, we already have the general view of this specific structure, right? Or based on this specific alky group, we just want to give the condensed formula and condensed formula simply means that we don't want to show any of those bonds, right? We want to write it in a single line as though it was some text. So what we can do is simply state ch three CH two and that's it. We're going to add that line showing some potential bonding to something else, right? But this is not technically really accurate, it is perfectly fine, but it's not really accurate because the bond is pointing from hydrogen. So we want to slightly modify it and we want to state that it is actually the carbon atom that is bonded to the parent, right? And this leaves us with two hygen on the left instead of the right hand side. And now we simply want to add CH three, which makes it much more accurate. As we can see, we still have two carbons and we have five hygen. But this representation is much more accurate because it shows the actual bonding. We generally want to avoid the bond pointing from the atom that is not involved in the bonding. And we have our final answer. Thank you for watching.
