Concept explainers
(a)
Interpretation: All the staggered and eclipsed conformations of each given molecule that would result from the rotation around the highlighted bond are to be drawn.
Concept introduction: Conformational isomers are defined as the type of stereoisomers in which the rotation about single bonds forms different spatial arrangements of atoms. It is of two types, eclipsed conformation and staggered conformation.
In Newman projection, the carbon in front is represented by a point and in the back is represented by a circle.
(b)
Interpretation: The graphs of energy versus dihedral angle for rotation around the highlighted bond of each given molecule are to be drawn.
Concept introduction: Newman projection is a visual representation of a conformation. It describes three groups which are attached to each carbon atom in a particular

- Draw the most stable conformer of the following molecule. (A solid wedge points out of the plane of the paper toward the viewer. A hatched wedgepoints back from the plane of the paper away from the viewer.)arrow_forwardQUESTION 3 (a) Draw the two conformations of ethane which has an energy minimum and energy maximum using the Newman projection. Explain why one conformation is lower in energy than the other.arrow_forwardQ2. Answer any TWO of the following parts: (a) Draw the two main conformations that exist for cyclohexane. Explain clearly why one conformer is more stable than the other. Using cis-1-ethyl-3-methylcyclohexane, as an example, explain how ring flipping occurs. Draw both conformers of cis-1-ethyl-3-methylcyclohexane and explain clearly which one predominates. (b) What is polarimetry? The specific rotation of (R)-carvone is - 61°. A chemist prepared a 750 mg mixture of (R)-carvone and its enantiomer in 10 ml of ethanol and placed the solution in a 10 cm polarimeter cell. The observed rotation was - 4.125°. Calculate the specific rotation for the above mixture. What is meant by enantiomeric excess? Then determine the % enantiomeric excess (% ee) in the mixture. (i) (ii) (iii) What % of the mixture is (R)-carvone and (S)-carvone?arrow_forward
- a) i) Draw the Newman projections for the conformations of ethane (staggered and eclipsed) Which is higher in energy? Which is more stable? Next to each conformer, draw the equivalent ‘sideways’ view, using wedged bondsarrow_forward3)) Draw the most stable chair conformation of a 1,2,4-trimethylcyclohexane (Show all the hydrogens and indicate if the bond is axial or equatorial at the substitution).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 arrow.arrow_forward
- Draw the most and least stable conformer of chloroethane and 1,2-dibromoethane.arrow_forwardConsider the tricyclic structure B. (a) Label each substituent on the rings as axial or equatorial. (b) Draw B using chair conformations for each sixmembered ring. (c) Label the atoms on the ring fusions (the carbons that join each set of two rings together) as cis or trans to each other.arrow_forwardFor the following two pairs of molecules, (1) Draw out the chair conformation for each molecule, flip the ring if it is possible. (2) Compare both molecules to circle out which one is more stable. (3) Identify their relationship as: constitutional isomer, conformational isomer, stereoisomer or identical. (4) Find all the chiral center on each molecule and label them. VS. ****arrow_forward
- Look at the model of chloroethane. a) Do all chloroethane molecules spend all of their time in this preferred conformation? Explain why or why not. b) What is the preferred conformation called?arrow_forwardSight along the C2-C1 bond of 2-methylpropane (isobutane).(a) Draw a Newman projection of the most stable conformation.(b) Draw a Newman projection of the least stable conformation.(c) Make a graph of energy versus angle of rotation around the C2-C1 bond.(d) Assign relative values to the maxima and minima in your graph, given that an H↔H eclipsing interaction costs 4.0 kJ/mol and an H↔CH3 eclipsing interaction costs 6.0 kJ/mol.arrow_forwardFor the molecule shown below, draw both chair conformations and circle which is the lower energy conformer. .CI "CIarrow_forward
