Question
Chapter 4, Problem 38P
Interpretation Introduction
Interpretation:
The energy changes from the rotation of C2-C3 bond of 2,3-dimethylbutane and 2,2,3,3-tetramethylbutane are to be determined with all the maxima and minima.
Concept introduction:
Chair conformation: It is the most stable conformation which accurately shows the spatial arrangement of atoms.
Equatorial bonds are parallel to the average plane of the ring while axial bonds are perpendicular to the average plane of the ring.
The conformation having bonds at equatorial position are more stable than those having at axial position.

2A2: Apply the concepts of stereocenters, chirality, asymmetry, and the CIP Rules to label enantiomers/ diastereomers and R/S or
E/Z absolute configurations.
These two (2) structures have ambiguous configurations. Provide a wedge and dash structure for the indicated configurational isomer. In
your response, keep the overall structural orientation the same as given. In addition, label all alkenyl FGs as either E or Z in both structures

(1) Predict the outcome of the addition of HBr to (a) trans-2-pentene, (b) 2-methyl-2-butene, and (c) 4-methylcyclohexene. How many isomers
can be formed in each case?
Compound X, C,4H12Br2, is optically inactive. On treatment with strong base, X gives hydrocarbon Y, C14H10: Compound Y absorbs 2 equivalents of
hydrogen when reduced over a palladium catalyst to give z (C14H14) and reacts with ozone to give one product, benzoic acid (C,Hg02). Draw the
structure of compound Z.
• Use the wedge/hash bond tools to indicate stereochemistry where it exists.
• Ignore alkene stereochemistry.
• If more than one structure fits the description, draw them all.
• Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner.
• Separate structures with + signs from the drop-down menu.
