# What is the Fisher projection of #\text{(s)}-3-\text{bromo}-3-\text{chlorohexane}#?

##### 1 Answer

Here's what I get.

#### Explanation:

The structure of 3−bromo−3−chlorohexane is

To get the 3D structure, I arbitrarily drew the wedge and dash as above (I had

a 50 % chance of getting it right).

If it turns out to be wrong, I will interchange

To get the Fischer projection, we draw the carbon backbone vertically with

Remember that the horizontal bonds must each be wedges.

We assign priorities as follows:

Luckily, the lowest-priority group (

The **(S)-3−bromo−3−chlorohexane**.

Note: you could also use condensed structural formulas for the groups above and below
