Document Summary
Dr. john c. vederas: structure and nomenclature - 56 points , draw structures for which names are given, or name the given structures by any correct (systematic or common) nomenclature. Be sure to give cis or trans (or if appropriate z or e) or r or s assignment to the isomer where indicated by asterisks (***). (4 points each: methylene chloride, isopropyl fluoride, neopentane, trans-1-cyclopropyl-2-methylcyclobutane. 4-butyl-3-methyl-3-undecene substituents in any order as long as numbers correct as given. *** 8. (e)-2,4,8-trimethyl-4-nonene will accept trans: determine whether the following pairs of structures are identical (i. e. different pictures of the same molecule), structural isomers, or stereoisomers (4 points each). 4: conformational drawings, draw the most stable conformation of the central bond of hexane using newman projection (4 points, draw the most stable conformation of the molecule shown below. If you make an error, please redraw the template. (4 points)
