Draw the following molecule and its ring flipped conformer in the chair conformation on a sheet of paper:
trans-1-chloro-2-methylcyclohexane
a) The spatial relationship between the Cl and the methyl C in the most stable chair conformation is:gauche/anti/eclipsed bonds with 120 degree dihedral angle /eclipsed bonds with 0 degree dihedral angle
b) The spatial relationship between the Cl and the methyl C in the least stable chair conformation is:gauche/anti/eclipsed bonds with 120 degree dihedral angle /eclipsed bonds with 0 degree dihedral angle
Draw the following molecule and its ring flipped conformer in the chair conformation and select the position that makes the statement true:
