In order to get elimination of HCl, the Cl onC2 and the β H must be in a trans diaxial conformation. If the Cl is axial, the isopropyl group on C1 is also axial and the β H on C1 is equatorial. There is no axial H on C1, because the isopropyl group has replaced it. The axial β H must therefore come from C3. ggc health portal https://neromedia.net
