A student was given a sample containing a mixture of stereoisomers of 3-bromo-4-fluorohexane that was contaminated and was asked to identify all of the possible stereoisomers of 3-bromo-4-fluorohexane that could be present so they could isolate the contaminant. Draw the four possible stereoisomers of 3-bromo-4-fluorohexane.

Explanation:

From the given information;

The objective is to draw the four possible stereoisomers of 3-bromo-4-fluorohexane.

Stereoisomerism is the difference of the spatial arrangement of atoms in a molecule or a compound with the same molecular formula.

For 3-bromo-4-fluorohexane, We have the stereoisomers as follows:

(3S, 4S)-3-bromo-4-fluorohexane

(3S,4R)-3-bromo-4-fluorohexane

(3R, 4R)-3-bromo-4-fluorohexane

(3R, 4S)-3-bromo-4-fluorohexane

The above four possible stereoisomers are drawn and can be seen in the file attached below  in a respective order.
