A trisubstituted cyclohexane compound is given below in its chair conformation. Draw the corresponding planar (overhead) representation, using wedge-and-dash bonds to indicate the substituent positions. To be graded properly, include the hydrogen atoms on the chirality centers (asymmetric carbons). Be sure that both wedge/dash bonds are drawn on the outside of the ring, or else the stereochemistry may be interpreted as square planar.

    ok do you know how to go from chair form to the ring?

    i do. I am having trouble with where the hydrogens go.

    I will start by showing you how to go from chair form to the ring

    Okay so the first thing, is that a dashed line means that the group is away from you, and a wedge means that the group is pointing straight at you. |dw:1441924577768:dw|

    When you have your chair form you MUST number the carbons

    Number your carbons and draw the chair form like this. it is important to note whether the groups are up or down. up = wedge on your cyclohexane ring, down = dash |dw:1441924908351:dw|

    A dash means up a wedge means down on your flat ring. you draw out your cyclo hexane in chair form number the carbons in both the flat ring and the chair form and then, translate as follows. |dw:1441925042869:dw|

    I see that you have both fluorine and bromine as dashes and that chlorine is a wedge

    your figure is correct to me, they are in similar positions

    hmm did they ask for the most stable ?

    no. are the hydrogens on the correct carbons?

    the thing with online websites is that if it's not 100% the exact way that they want it they'll mark you wrong. i think you should show the hydrogen as a dash behind the chlorine

    I'll try that. Thanks for your help.

    absolutely, I mean you did everything correctly but FYI this isn't the most stable structure

    the easiest thing to do is to 1. number the carbons on the ring 2. a dash on the ring is always up and a wedge is always down 3. number carbons on the chair 4. any groups pointing upwards on the chair will be a wedge on the ring 4. any groups pointing downwards on the chair will be a dash on the ring
