In this chemistry lab, you will be determining the r/s orientation of the indicated carbons in this molecule. To do this you will need to use the VSEPR theory to predict the carbon’s orientations. This is a very important theory in organic chemistry and it can help you understand how molecules are composed.
The Rotation of the Carbons in Methyl Chloride
Methyl chloride is a molecule made up of one carbon atom and three hydrogen atoms. The carbon atom is located on the left side of the molecule, and the hydrogen atoms are located on the right side. This means that the carbon atoms are oriented in a clockwise direction around the molecule.
The molecule shown has the carbons oriented in a r/s configuration.
What does R denote?
The R in r/s stands for “rightmost” and refers to the carbon atom that is furthest to the right in the molecule.
