Concept explainers
(a)
Interpretation:
The relationship of given compound with the compound in Figure 7.3 should be stated.
Concept Introduction:
The compounds that have same molecular formula but have different arrangement of atoms in a space are known as isomers.
Conformers are obtained by the interconvertion of a molecule without breaking the bond through the rotation about a single bond. Consitutional isomers have same molecule formula but have different connectivity of atoms. The compounds that have same molecular formula and also have the connectivity of atoms but cannot be converted into one another by rotation about a single bond are known as configuratiol stereoisomers.
(b)
Interpretation:
The purpose behind to dermine the name of each molecule before to identify reactionship of each molecule with cis-1,2-dimethylcyclohexane should be predicted.

Organic Chemistry: A Guided Inquiry
- a. For each disubstituted cyclohexane below, draw its ring-flip isomer. Circle the most stable conformation and label the substituent groups as axial or equatorial. ( see image) b.Draw and name the seven constitutional isomers (all contain a ring of some size) for cycloalkane, C6H12.arrow_forwardImagine that this worksheet has sucked you the plane of the page, and you are now facing the indicated bond of the drawn molecule. a. Draw the six main Newman projections for the indicated bond: three eclipsed, three staggered. b. Label which conformers are eclipsed ands taggered.c. Identify the most and least stable conformer, and explain your reasoning.arrow_forwardCreate a conformational analysis using the molecule in the picture. Follow the instruction in the picture when you transform the molecule into its Newman projection. Which conformer is the most stable? Explain.arrow_forward
- Create a conformational analysis using the molecule in the picture. Follow the instruction in the picture when you transform the molecule into its Newman projection. Which conformer is the most unstable? Explain.arrow_forwardI know the answer is correct but I can’t figure out if C is tertiary ? It can’t be secondary because it has more than two carbons connected to the +Carrow_forwardCreate a conformational analysis using the molecule in the picture. Follow the instruction in the picture when you transform the molecule into its Newman projection. Explain the conformations.arrow_forward
- 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).arrow_forwardDraw Newman projects of all the staggered conformations for the molecule below looking along the bolded bond in the direction indicated by the arrow. The carbon closest to the arrow should be the front carbon of your Newman projection. (It is a practice problem from the book but I am confused about how to approach it.)arrow_forwarda. Draw the lowest energy conformation for the compound shown in the image. b. Draw the complete structural formula of the following compound: cis-1-bromo-3-chlorocyclohexane.arrow_forward
- Identify and label all functional groups Identify and label all stereo centersarrow_forwardConstruct a model in which a tetrahedral carbon atom has four different colored model atoms attached to it- red, green, orange and white representing 4 different atoms attached to the central atom. a) Does the atom have a plane of symmetry? why or why not? b) Now replace the green atom in your model with a second orange atom. Now two of the groups attached to the carbon atom are identical. Does the model now have a plane of symmetry? Describe it. c)A carbon atom has four different groups attached to the stereogenic center. Draw structural formulas for the following compound and mark stereogenic centers with as asterisk: 1-bromobutane, 2-bromobutane, 1,2-dibromobutane, 1,4-dibromobutane, 2,3-dibromobutane.arrow_forwardDraw the Newman projection so that it corresponds to the molecule and conformation shown when viewed down the red bond in the direction of the red arrow. Your projection should be oriented as shown by the arrow marked up. So the CH2SH group on the front carbon should be above the H and H3C groups, no matter which template you usearrow_forward
