Welcome back, everyone. Draw the structure of hex and we own according to the name of the structure. If we look at the suffix on essentially represents a ket zone, that's what we want to recall in this problem. And the general form of ketones would be the Kanal group co bonded to two LK groups are one and are two. Now, essentially our parent is Hexagon. It essentially means that we have a total of six carbon atoms in our parent chain. So what we're going to do is just draw a six member chain 123, four, five and six carbon atoms. And what we want to do here is just bond a carbon group at carbon number three because it says three on. So if we count our carbon atoms, we have 12 and three. So let's simply introduce a carbon group, add carbon number three. And this is how we get our structure. We have a total of six carbon atoms in the parent and there's a carbon group at carbon number three. Let's label the structure as our final answer. And thank you for watching.
