5.3—The E–Z naming system for geometric isomers and why it is necessary to use this when the cis- and trans- naming system

Understand the E–Z naming system for geometric isomers and why it is necessary to use this when the cis- and trans- naming system breaks down.

Use —the e–z naming system for geometric isomers and why it is necessary to use this when the cis- and trans- naming system to connect the rule to the data and decision in the question.

This matters because —the e–z naming system for geometric isomers and why it is necessary to use this when the cis- and trans- naming system determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —the e–z naming system for geometric isomers and why it is necessary to use this when the cis- and trans- naming system to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —The E–Z naming system for geometric isomers and why it is necessary to use this when the cis- and trans- naming system is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
