- Label each of the following as cis, trans or neither. Below each structure that is cis draw a transconfigurational stereoisomer or vice versa.For mono-substituted cycloalkanes the “1” is not included. That is, the name1-methylcyclohexane is not correct. The correct name is simply “methylcyclohexane”. a. Draw methylcyclohexane. b. Explain why adding a “1” to methylcyclohexanedoes not add any new information.Scoring: Your score will be based on the number of correct matches minus the number of incorrect matches. There is no penalty for missing matches. Match the condensed structural formula on the left with the molecular structure on the right. Clear All CH3CONH2 C6H5COOH CH3CH2CH2OH CH3COOCH2CH3 C6H5CH2NH2
- For the attached question (a), do the positions of the H and CH3 of the back carbon matter? Can they be switched since the front carbon is 'symmetrical' with two hydrogens?This problem considers the conformational isomers of 2-methyl-butane shown below. The label for each carbon is indicated in red. Also shown is the Newman projection for the bond between carbons 2 and 3. The Newman projection is shown at its 0o position. The angle increases with clockwise rotation of the bonds on carbon 2. Which rotation angle(s) has(have) the lowest energy? (select all that apply) Which rotation angle(s) has(have) the highest energy? (select all that apply). Which rotation angle(s) has(have) a local anergy minima that is(are) not the lowest energy possible? (select all that apply).Check the box under each structure in the table that is an enantiomer of the molecule shown below. If none of them are, check the none of the above box under the table.
