6. Draw and name all the alkene cis-trans isomers corresponding to the molecular formula C5H10. (Hint:...
same compound, constitutional isomers (structural
isomers), cis-trans isomers, not isomers
(different molecular formula).
Br a Br C C and Br Br
How many linear dienes have molecular formula C7H12? (Disregard cis-trans isomers.)
Name the alkene(s) with the molecular formula C6H12 that have a single methyl branch and that show E/Z isomerism. Use E/Z to describe stereochemistry around the double bond as appropriate. Do not use cis/trans. If there are fewer than 4 possible isomers, leave the appropriate number of spaces blank.
For the molecule whose condensed structural formula is given below, decide if cis-trans isomers are possible. If they are, enter the name of the cis isomer in the first box and the name of the trans isomer in the second box. If cis-trans isomers are not possible, enter the name of the compound in the first box and leave the second box blank. Do not attempt to put cis or trans in italics. CH3CH2CH=CH2
5.22 Draw a structural formula for an alkene with the indi- cated molecular formula that gives the compound shown as the major product. Note that more tharn one alkene may give the same compound as the major product. OH HoSO4 (a) C5H10 H2O (b) C5H10 + Br2 → Br (c) C7H12+HCI-→ Cl
Which of the following pairs are cis-trans isomers? Select all the pairs that are cis-trans isomers.
including cis- trans isomers, how many different alkenes have the molecular formula C 4H 8? a.3 b.4 c.5 d.2
2. Draw the structures of the cis-trans isomers for each compound. Label them cis and trans. If no cis-trans isomers exist, write none. a. 2,3-dimethyl-2-pentene b. 1,1-dimethyl-2-ethylcyclopropane c. 1,2-dimethylcyclohexane d. 5-methyl-2-hexene e. 1,2,3-trimethylcyclopropane
