I have a problem which gives 3 names and I have to draw structures for them and then give names which would be more apt (easier to understand)
There are 3:
I know c is benzene (and I can draw it.. obviously), but I'm a little stuck on the first two.
For a, the base structure I know is benzene, but the first part is confusing me. Does methylethyl mean propyl? I know the 1,4 is telling me it will be para something benzene but the di and methylethyl is confusing me. The repeated 1's are what is really getting me. Does this mean on carbons 1 and 4 will be a methylethyl (propyl) group? If so then I know how to draw it, and I would call it para-propylbenzene? It sounds right to me and makes sense, just a little confusd about how exactly I would know that.
For b, I think the base structure is propene with a double bond on the first carbon, and then on the second carbon there is a propyl group attached. Then the propyl group has a double bond on the 2nd carbon (-ENyl), but is it to the oxygen or to the carbon (not the carbon on the propane, the third carbon on the propenyl group). So perhaps it would be 2-methylbut-1-en-3-one? But that isn't much simpler so I don't think its right. Any hints are appreciated.
