The structural formula of 2‐bromo‐3‐chlorobutane is

www.docbrown.info

It gives no stereochemical information.

You can find the general procedure for drawing sawhorse projections at this location.

The sawhorse structure is

The methyl groups are at the ends of the vertical bonds, the Br atom is on C-2, and the Cl atom is at C-3.

Note that C-2 and C-3 are chiral carbons, so this is only one of the four possible stereoisomers of 2-bromo-3-chlorobutane.
