For the cyclohexanes substituted in the positions indicated, identify the substituents as either axial or equatorial in chair conformers. For example, a 1,2-cis relationship means that one substituent must be axial and one equatorial.
label each one as: both axial, both equatorial, both axial or both equatorial, or one axial and one equatorial
a) 1,6-trans-disubstituted
b) 1,5-cis-disubstituted
c) 1,4-cis-disubstituted
