Given the wedge-and-dash structure of $2_{}$-bromobutanol with the following configuration: the hydroxyl group ($\mathrm{OH}$) is on a wedge at carbon 2, the bromine ($\mathrm{Br}$) is on a dash at carbon 2, and the methyl group ($\mathrm{CH}{3}_{}$) and hydrogen are in the plane, which Fischer projection correctly represents this molecule?

Examine the Fischer projection below. How is this carbohydrate classified?
CHO at top, then $H-C-OH$, then $HO-C-H$, then $H-C-OH$, then $CH{2}_{O}H$ at bottom'>

Convert the Fischer projection to a perspective formula.

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.
