4- Use Newman projections to represent the most stable conformer for the
following molecules (remember to assign Gauche interactions).

HN
If you rotate the hydrogen atoms to a different position in a a model of C2H6 by turning about the central C—C bond, do you get different structural (or constitutional) isomers of C2H5Cl?
Draw the structural isomers of C2H4BrCl and identify which of them has a chiral center. Then, create the Newman projection of the most stable conformational isomer and indicate its absolute configuration.
