How are Fischer projections drawn?

To find the enantiomer of a molecule drawn as a Fischer projection, simply exchange the right and left horizontal bonds. To determine whether the molecule in Fischer projection is a meso compound, draw a horizontal line through the center of the molecule and determine whether the molecule is symmetric about that line.

What is the Fischer projection formula?

Fischer projection formula or cross formula : The three dimensional (3-D) view of a molecule is presented on plane of paper. A Fischer projection formula can be drawn by visualizing the main carbon chain verical in the molecule. Each carbon on the vertical chain is represented by a cross.

What is Fischer projection formula?

What are the hardest things to draw in cycloalkanes?

Cycloalkanes can be one of the hardest things to draw in this class. First we will address the Haworth projection, What is the chair conformation? Because there are six sp3 hybridized carbons in a cyclohexane ring, the chair conformation becomes the most stable conformation.

How do you draw stereoisomers with a Fischer projection?

Fischer projections make it easy to draw different stereoisomers. As an example, if you are asked to draw the enantiomer of the following molecule with three chiral centers, you can draw an imaginary mirror plane and draw the reflection of the molecule, which is achieved simply by swapping the two group of a chiral center:

What order should I number the carbons in my Fischer projection?

Before getting to drawing its Fischer projection, lets number the carbons in any order (no IUPAC rules needed). Remember, numbering carbons will always be helpful no matter what you need to do with an organic structure.

How do you find the chirality center in Fisher projection?

In Fisher projection, the chirality center is shown as the intersection of two perpendicular lines. The horizontal lines represent the bonds point out of the plane, and the vertical lines represent the bonds that point behind the plane.
