I think 2 and 4 are the same... Both can be read as 2-bromobutane, please look at them carefully, you'll see. I don't consider enantiomer formation, as there should be 2S-2-bromobutane and 2R-2-bromobutane, because they are not isomers, enantiomers, i.e., optical isomers.

About drawing formulae, I am not sure, but our moderator can show us how to arrange LateX to draw these formulae. It is possible, I know. If it isn't, it would be better for you to obtain some freeware chemical drawing software like ChemSketch or Isıs-Draw.
