1. Construct a model of the 2,3-dibromopentane isomer and label the chiral centers as R or S. Then make a model of its mirror image and draw it below, again labeling the chiral centers as R or S. a. Convert both models to their most stable conformation and draw their Newman projections looking down the center bond. b. On one model interchange the H and Br on one of the chiral centers. How is this molecule related to the other...
please help with the questions.

For 2-chloro-3-hexanol: Draw the structure of all the possible stereoisomers with Fischer Projection and Perspective Formulas showing both eclipsed and staggered conformations). 2) Assign the configuration of all chiral centers with R or S. (3) Give the complete IUPAC name for each stereoisomers. (4) Indicate the relationship among the structures, indicating which are the threo or erythro enantiomer, and diastereoisomer pairs.
Consider the molecule shown below. ch_2ohchohchohch_3, Indicate chiral centers and predict the total number of stereoisomers. Draw them out in the Fischer projection. Build a model of one of them (orient it in the Fischer projection) so you can visualize the shape and how the chain curves. Sketch it to the best of your ability. Which of the molecules are enantiomers of each other? Are there any meso compounds? Justify your answers and draw them out. Take a pair of...
