Draw the skeletal structure for each of the following compounds:

(a) 2,3-dimethylpentane

Video transcript

Welcome back everyone to another video draw the skeletal formula of 34 di ayl hete. The given structure is an L Kane because we can clearly see that at the end of the name we are given A&E, right? So let's understand that the parent is heptane overall. And heptane means that we have a total of seven carbon atoms in the parent, right? Hep as a prefix means seven. Now, the easiest way to begin solving this problem is to draw a seven member chain and remembering that scale of formulas, they have implicit carbons at the corners and the vertices of the structure. So we can draw one carbon atom followed by the second one, the third one, the fourth one, the fifth one, the sixth one and then the seventh carbon atom. So we have drawn a total of seven carbon atoms in the longest continuous chain. And now we can focus on the subscriptions at the beginning of the name. We can see three comma four th ethel. Now, what does that mean? Well, basically it states that carbon we and four, they have two because of dye ethyl groups, right? So if we simply enumerate the parent. We can see that we have carbons 123456 and seven. We simply want to add two ethyl substituents to carbons three and four. And we want to recall that an ethyl substituent is simply a two member chain. So we can add one carbon followed by the second one, add carbon three and we can repeat the process for carbon four and that's it. We have got the final structure. Thank you for watching.
