Question

part 1 (1 point) see periodic table part 1 part 1: re - draw the first cyclohexane in the chair conformation. modify the standard chair conformation shown by replacing the hydrogen atom(s) with the appropriate substituent. use the carbon atom labeled with an asterisk as a reference for the position of the atoms on the ring

Explanation:

Step1: Recall chair - conformation rules

The chair - conformation of cyclohexane has axial and equatorial positions.

Step2: Identify positions of substituents

The two methyl groups in the given cyclohexane need to be placed in the correct positions in the chair - conformation. One methyl group is attached to the carbon with the asterisk and the other is at a neighboring carbon.

Step3: Draw the chair - conformation

Draw the standard chair - conformation of cyclohexane first. Then, based on the reference carbon (the one with the asterisk), place the methyl groups. If the methyl group on the carbon with the asterisk is in an axial (or equatorial) position in the original structure, place it in the corresponding axial (or equatorial) position in the chair - conformation. Do the same for the other methyl group.

Answer:

(It is not possible to directly draw in this text - based format. But the steps above describe how to re - draw the cyclohexane in chair - conformation. One would draw a standard chair - shaped hexagon and place the methyl groups in the appropriate axial or equatorial positions according to the reference carbon.)
