Question

identify the axial/Equatorial nature of the groups Identify the cis-, trans- relationship of the two groups, and identify the axial/equatorial nature of the groups. More than one answer must be indicated for full credit. This compound should be properly called trans-1,3-dibromocyclohexane. Both bromine atoms are in an axial conformation. This compound should be properly called cis-1,3-dibromocyclohexane. Both bromine atoms are in an equatorial conformation. One bromine atom is in an axial conformation, while the other bromine atom is in an equatorial conformation.

Explanation / Answer

Both the bromines are in alpha plane i.e. below the plane in the cyclohexane ring. So both the bromines are in cis to each other. So the compound should be properly called cis-1,3-dibromocyclohexane.

Now both the bromines are in equatorial position in the cyclohexane. So both the bromine atoms are in an equatorial conformation.
