Make a model of 1,2-dichloroethyne, Are cis and trans isomers possible here?
PART B: Cyclohexane Procedures: 1. Make a model of cis-1,2-dimethylcyclohexane and trans-1,2-dimethylcyclohexane. Do a ring flip of both *Draw the two conformation of the cis and trans cyclohexane structures above *List the number of axial and equatorial substituents for both the cis and trans *Which isomer is more stable overall, cis or trans? Why? 2. Make a model cis-1,3-dimethylcyclohexane and trans-1,3-dimethylcyclohexane. Do a ring flip *Draw the two conformation of the cis and trans cyclohexane structures above *List the number...
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
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
How many constitutional isomers are possible in the dichlorination of cyclohexane? (Don't include cis/trans isomers as these are geometric isomers, although these are certainly possible with a cyclohexane ring.) 2 4 6 3 5
For each molecule, indicate whether cis-trans isomers exist. If they do, draw the two isomers and label them as cis and trans. a. CH3 - CH2 -CH=CH, b. CH3-CH2-CH=CH c. 2-Pentene d. 1,2-Dichloroethene
Which of the following pairs are cis-trans isomers? Select all the pairs that are cis-trans isomers.
#4. 2-pentene and 2-methyl-2-butene are not isomers stereoisomers constitutional isomers cis and trans isomers #6. Bromination of cyclohexene gives 1,2-dibromocyclohexane 1,1-dibromocyclohexane bromocyclohexane 1,2-dibromocyclohexene
Exercise 2: Geometric isomers. Build plastic models of cis- and trans-1,2-dibromoethene. Confirm that the two models are not superimposable. (2) For Draw a top view (atoms in plane) and side view (wedge) for each structure. Exercise 3: Cyclohexane. Build a plastic model of cyclohexane and rotate all C – C bonds into the staggered conformation. (3) Sketch the chair conformation you have constructed.
Which can have cis/trans isomers? and why? (1). 1,2,3-trimethylcyclopropane (2.) 1,2-dimethylbenzene (3.) 2,3-dimethyl-4-decene
How many cis/trans isomers are possible for 2,4,6-octatriene? O 3 OOO o o
