How do you convert Fisher projection formulae into wedge and dash formulae?

Answer 1

In a Fisher projection, vertical lines represent that the group is going into the page (dashes). Horizontal lines on a Fisher projection represent a group coming out of the page (wedges). Think of the horizontal lines like a bow tie--it looks like a wedge! |><|

Answer 2

To convert a Fischer projection into a wedge and dash formula, you rotate the molecule to position the horizontal groups as wedges (pointing towards you) and the vertical groups as dashes (pointing away from you). The orientation of the groups in Fischer projections (up or down) dictates their placement as wedges or dashes. Remember, dashes represent bonds going away from you, while wedges represent bonds coming towards you.
