Flip the projection clockwise. CH3 goes on top of Fischer and Cl goes at the bottom of the Fischer.
If one group at both the chiral centres point vertically down
- Flip the newman projection anticlockwise
- Front Carbon goes down and rear carbon goes up in Fischer projection
- The vertical groups are written on the vertical lines of Fischer projection
- The groups on left and right in newman projection are written on left and right in the Fischer projection
