So in this two chair structure when isopropyl group is at axial position there is 1,3 diaxial reputation because isopropyl is more bulkier group. So when isopropyl at equitorial position there is no 1,3 diaxial reputation between isopropyl. But there methyl group at axial position but methyl group is less bulkier so isopropyl group at equitorial position is more stable chair confirmation.
