15.2—Optical isomerism results from chiral centre(s) in a molecule with asymmetric carbon atom(s) and that optical isomers

Understand that optical isomerism results from chiral centre(s) in a molecule with asymmetric carbon atom(s) and that optical isomers (enantiomers) are object and non-superimposable mirror images and be able to draw 3D diagrams of these optical isomers.

Use —optical isomerism results from chiral centre(s) in a molecule with asymmetric carbon atom(s) and that optical isomers to connect the rule to the data and decision in the question.

This matters because —optical isomerism results from chiral centre(s) in a molecule with asymmetric carbon atom(s) and that optical isomers determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —optical isomerism results from chiral centre(s) in a molecule with asymmetric carbon atom(s) and that optical isomers to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —Optical isomerism results from chiral centre(s) in a molecule with asymmetric carbon atom(s) and that optical isomers is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
