16. Draw and name at least 4 structural isomers of C5H10O2. Be sure to include at least 2 different functional groups.

1. a. Draw and name the five cycloalkane structures of formula C5H10. Can any of these structures give rise to geometric (cis-trans) isomerism? If so, show the cis and trans stereoisomers. b. Draw and name the eight cycloalkane structures of formula C6H12 that do not show geometric isomerism. c. Draw and name the four cycloalkanes of formula C6H12 that do have cis-trans isomers. 2. Each of the following descriptions applies to more than one alkane. In each case, draw and name two structures that match the description. (a) an isopropylheptane (b) a diethyldecane (c) a cis-diethylcyclohexane (d) a trans-dihalocyclopentane (e) a (2,3-dimethylpentyl)cycloalkane (f) a bicyclononane   3. 2. refer to the photo attached and answer the ff.3-33, 3-34
