When it comes to organic compounds, we can see that they have a lot of structural diversity. Now here we can say this is a result of carbon. Carbon can make very stable carbon-carbon bonds due to high bond energy and short bond length. This leads to the formation of chains, branched structures, and rings in organic compounds.

So here let's just take a look at some of these examples of structural diversity. So if we take a look here, we have a hydrocarbon. It's composed of only carbons and hydrogens. It is a straight chain. So we have these four carbons in a chain together and they just have these hydrogens branching off of them. Well, they're not branching groups, they're coming off of the carbon. The carbons themselves are a straight chain.

Now if we take a look at the next one, we have these carbons in a straight chain and now we have a carbon that's off of the main chain, that's a branching group. Here we'd have this Chapter 3 portion as a branching group. And then finally we have a ring where the four carbons, they form a square. Here they form a cyclic or ring structure.

So remember carbon-carbon bonds can happen and form these different types of structurally diverse molecules or compounds because of high bond energy and short bond length.
