Document Summary
Know how to draw at ring and chair conformations for molecules. Test will be on chapter 3, 4, ir, and some questions from chapter 5. When alkanes contain two fused or bridged rings: rst count how many total carbons are there in total. Need to count how many carbons between the two bridgeheads are there, and how many bridges there are: ex. bicyclo[2. 2. 1]heptane. How to name alkenes & cycloalkenes: alkenes. Change the ending of the naming to -ene. Number where the c=c bond begins: cycloalkenes. The c=c bonds always have priority in numbering for cycloalkenes. No need to put 1 before the -ene, because it"s assumed that the alkene is 1,2: alkenes vs alcohols. Alcohols always have priority over alkenes: get the lower number and get the suf x -ol. Vinyl group and allyl groups: vinyl groups. When there is a group connected directly onto a alkene: the alkene becomes the vinyl group, allyl group.
