Identifying Chiral carbons. Identifying chiral carbons in a molecule is an important skill for organic chemists. The presence of a chiral carbon presents the possibility of a molecule having multiple stereoisomers.
What is a chiral carbon, chiral carbons in rings, and how to find chiral carbon centers in a matter of seconds. In this tutorial, I share tips and tricks for...
The easy way to determine if a molecule is chiral is simply to look for the presence of one or more chiral centers: molecules with chiral centers will often be chiral. We can not say ‘always’ here because it is possible to come up with exceptions to this rule.
This article explains how to identify chiral carbon atoms in a molecule in aliphatic structures or ring structures. The presence of chiral carbon indicates that it has stereoisomers. This is very important in observing the relationships and reactions of molecules.
Rules for assigning an R/S designation to a chiral center. 1: Assign priorities to the four substituents, with #1 being the highest priority and #4 the lowest. Priorities are based on the atomic number. 2: Trace a circle from #1 to #2 to #3. 3: Determine the orientation of the #4 priority group.

How can I identify chiral and achiral molecules? Look for #sp^3# carbons; those tend to be the most prevalent indications of chirality or achirality. You can ignore many #sp^2# alkene carbons.
Identify the following as either a constitutional isomer or stereoisomer. If stereoisomer, determine if it is an enantiomer or diastereomer. Explain the reason behind the answer.
Practice finding chiral carbons in a variety of organic molecules.
This organic chemistry video tutorial explains difference between chiral molecules and achiral molecules and how to find them by drawing a line of symmetry. ...
