(iii) if either, is more stable? Which isomer, cis or trans, is...
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
4. Draw the following cycloalkanes as two-dimensional structures, using wedges and dashes: trans-1-bromo-2-methylcyclopentane cis--chloro-3 ethylcyclohexane trans-1,3-dimethylcyclohexane trans-1-bromo-3 ethylcyclobutane cis-1-ethyl-4-methylcycloheptane cis-1-isopropyl-3- methylcyclopentane
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
Draw the structure for the following compound using wedges and dashes. trans−1−ethyl−2−methylcyclopentane
11/8/19 The cis- and trans-isomers of 1-bromo-2-methylcyclohexane are shown below. One of these isomers undergoes E2 elimination 50 time faster than the other. Illustrate the E2 mechanism using the chair conformers to explain why one isomer is much faster and give the major product of each reaction. 1-BUOK 1-BOK Illustrate the Sw2 mechanism for the reaction below and show what has happened to the stereochemistry of the compound. NaCN acetone
The cis and trans geometric isomers of a compound can have different chemical and physical properties. Draw the structure of the geometric isomer of 2-pentene that has the lower melting point.
4th сутеплите. 3. Build the models and draw the cis and trans isomers of the following compounds. (c) 1-ethyl-3-methylcyclohexane 1,3-dimethylcyclopentane 1,2-dimethylcyclobutane 4. Build the cyclopropane ring and find the source of angle strain and torsional strain in the ring. Draw the relevant structures to explain these factors.
