5.2—Geometric isomerism in terms of restricted rotation around a C=C double bond and the nature of the substituents on

Be able to explain geometric isomerism in terms of restricted rotation around a C=C double bond and the nature of the substituents on the carbon atoms.

Use —geometric isomerism in terms of restricted rotation around a c=c double bond and the nature of the substituents on to connect the rule to the data and decision in the question.

This matters because —geometric isomerism in terms of restricted rotation around a c=c double bond and the nature of the substituents on determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —geometric isomerism in terms of restricted rotation around a c=c double bond and the nature of the substituents on to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —Geometric isomerism in terms of restricted rotation around a C=C double bond and the nature of the substituents on is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
