Unformatted text preview: trans-1-isopropyl-3-methylcyclohexane. Begin as in part ( c ) by placing an isopropyl group in an equa-torial orientation on a chair conformation of cyclohexane. To be trans to the C-1 isopropyl group, the C-3 methyl group must be up. The bulkier isopropyl group is equatorial and the methyl group axial in the most stable conformation. ( e ) To be cis to each other, one substituent must be axial and the other equatorial when they are located at positions 1 and 4 on a cyclohexane ring.
