Chapter 3 Problem #4
a) To begin this structure you'll start with a pentene ring, hence the prefix "cyclo-". We then place the double bond between carbons 1 and 2. Lastly, for the "dimethyl", we place two methyl groups on carbon 3.
b) For this structure you begin with a carbon chain with 6 carbons. A bromine atom can be added to the end or beginning of the chain depending on which way you number your carbons. The double bond can then be placed between the 2nd and 3rd carbon because of the "2-hexene". Finally, two methyl groups will be placed on carbons 2 and 3 to fulfill the "dimethyl".
c) The first thing to recognize in this structure's name is "ether". This insinuates that there will be an oxygen between two carbons. Vinyl means that the oxygen will be attached to the carbon on the triple bond. Finally, an ethyl group would also be attached to the other side of the oxygen.
d) Alcohol in this compound's name automatically means there will be an -OH in the structure. However, the allyl part means the -OH will be attached to the carbon next to the carbon with the double bond.
