Convert the Fischer projection to a perspective formula.

Are the following pairs identical, enantiomers, diastereomers, or constitutional isomers?

c.

d.

For each pair, give the relationship between the two compounds. Making models will be helpful.

(g)

Convert the Fischer projection to a perspective formula.

Convert the following perspective formulas to Fischer projections.

(a)

(b)

For each Fischer projection,

1. make a model.

2. draw the mirror

3.. determine whether the mirror is the same as, or different from, the original ­structure.

4. draw any mirror planes of symmetry that are apparent from the Fischer projections.

(c)

(d)

For each set of examples, make a model of the first structure, and indicate the relationship of each of the other structures to the first structure. Examples of relationships: same compound, enantiomer, structural isomer.
