15.1—Optical isomerism is a result of chirality in molecules with a single chiral centre

Know that optical isomerism is a result of chirality in molecules with a single chiral centre.

Use —optical isomerism is a result of chirality in molecules with a single chiral centre to connect the rule to the data and decision in the question.

This matters because —optical isomerism is a result of chirality in molecules with a single chiral centre determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —optical isomerism is a result of chirality in molecules with a single chiral centre to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —Optical isomerism is a result of chirality in molecules with a single chiral centre is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
