Why this is cis( 1tert.....).. although tert and methyl group are in equatorial position butyl-3-methylcyclohexane

7 CH3 ring flip CH3 CH CH CHa CH CH CH3 more stable ess stable cis-1-tert-butyl-3-methylcyclohexane

See the orientation of the substituent. If both are in same direction then it is cis

groups at equatorial position are more stable than Axial position because there is no 1,3 diaxial interconversions on equatorial position

bulky tertiary butyl group at equatorial position is stable. if it is in axial position 1,3 diaxial interaction is present...he certainly it is unstable at axial

At equatorial position, substituents is free from diaxial interactions...so it tends to be more stable at equatorial position...
