Why bulky group present at axial position of chair or boat conformer is less stable compared to equitorial position?
Ans) Let the bulky group has a large mass M.suppose it is at the axial point at a distance r from the centre.then the torque apllied is=r.M.ghence torque is proportional to the distance fom the centrelarger the distance more the torque and less is the stability of boat or chair.
