Drawing Enantiomers

Drawing Enantiomers - One enantiomer cannot be superimposed on the other. Web the lesson is that enantiomers are stereoisomers. Web if you draw an enantiomer using a mirror behind the molecule, you can simply spin the enantiomer around (180 degrees around the y axis) and it will be as if you drew the mirror to the side of the original molecule. Then, the vertical bonds above and below that bond are behind the plane of the paper. Web usually, we look at a fischer projection so one of the vertical bonds to a chiral carbon is in the plane of the paper. There are two approaches to solve this problem: This is not a universal solution though because the wedge and dash representation is relative and depends on the direction we are looking from. Now, not all the stereoisomers are enantiomers.

Stereoisomers Are Also Divided Into Two Main Groups.

The stereoisomers are any two molecules that fulfill the following two requirements: At the core of drawing enantiomers is identifying the chiral center in the molecule. Web an individual molecule is an enantiomer or a diastereomer of another molecule — i.e. We're going to assign an r ors to each of our enantiomers so let's start with step one.

The Stereocenters Are Labeled As R Or S.

The mirror plane can be vertical, horizontal, or even the paper where you draw the molecule can be the mirror plane itself. The rs system is used to describe the configuration of a chirality center. One should be an epimer. Web how to draw enantiomers.watch the next lesson:

Ii) If It Is Counterclockwise It Is S.

Proceed from 1 to 2 to 3. On the left we have one compound, on the right we have its mirror image. It’s enantiomer is that molecule in which all 10 stereocenters are inverted. When we move to a different chiral carbon we may choose to view the molecule eo a different bond is in the plane of the paper.

Remember Also That All The Chirality Centers Are Inverted In Enantiomers, Every R Is Changed To An S And Every S Is Changed Onto An R.

This is why jay talks about pairs of diastereomer*s* or enantiomer*s*. Web if you draw an enantiomer using a mirror behind the molecule, you can simply spin the enantiomer around (180 degrees around the y axis) and it will be as if you drew the mirror to the side of the original molecule. This is not a universal solution though because the wedge and dash representation is relative and depends on the direction we are looking from. I) if it is clockwise it is r.
