Question

Draw theSawhorsee and newman projections of trans 1,3 dibromo cyclohexane in chair form. Please include how you went from chair formation to sawhorse formation and then to new projection

And the substituted groups should be in the consecutive position through which you will see the C-atoms so that the upper and lower carbon dont bear those substituted groups (here Br). Because then you would not be able to show their cis and trans positioning.
