Question

Question: Draw each stereogenic center using a Fischer projection formula.

Short answer

Answer

(a)

(b)

(c)

(d)

Step-by-step solution

Stereogenic center

The location in a particular molecule where the swap of any two groups leads to a stereoisomer is termed stereogenic centers. They can be present in chiral or achiral molecules

Fischer projection formula

Fischer projection formulae are known by another name which is cross formulae. The horizontal bonds are specified as wedges, and the vertical bonds are specified as dashed wedges in a Fischer projection formula.

Drawing the stereogenic center using the Fischer projection formula

The molecule is rotated and redrawn to place the horizontal bonds in front of the plane and vertical bonds behind the plane. The vertical bonds are given as dashed wedges, and the horizontal bonds are given as dark wedges. The cross is utilized to indicate the stereogenic center.
