Evidence and Measurement

Connect the claim to observable evidence and state what uncertainty or limitation remains.

This extension applies that lens specifically to Organic Mechanisms.

Organic Mechanisms

Curved arrows track electron-pair movement through substitution, elimination, addition and carbonyl reactions.

Core checkpoint: Move electrons from a source to a sink and preserve charge.

Key idea

Move electrons from a source to a sink and preserve charge.

Key idea

Connect the claim to observable evidence and state what uncertainty or limitation remains.

Chemistry Year 2 — Evidence and Measurement: Which statement best captures the core checkpoint for Organic Mechanisms?

Move electrons from a source to a sink and preserve charge.

Choose a solution before defining the evidence.

Ignore units, limits and boundary cases.

Assume the first result applies in every context.
