From Acid To Alcohol and Back — Oxidise Up
1 alcohol reflux dichromate -> acid.
Learning objectives
- Define oxidise up using accurate chemistry terms.
- Explain why oxidise up matters within from acid to alcohol and back.
- Apply the learning unit to an FBISE-style example, comparison, diagram, or calculation.
Definition
1 alcohol reflux dichromate -> acid. Aldehyde also -> acid (Tollens conditions too). 2 alcohol stops at ketone. Interconversion map ties Ch18-21 synthesis. This page separates the idea from the wider topic “FROM ACID TO ALCOHOL AND BACK” so it can be revised and assessed on its own.
Important terms
- OXIDISE UP
- 1 alcohol reflux dichromate -> acid.
- FROM ACID TO ALCOHOL AND BACK
- Reduction of carboxylic acids is harder than of aldehydes (LiAlH4 named if the book has it; NaBH4 often not enough).
Overview
Study this learning unit in three steps:
Key Idea
1 alcohol reflux dichromate -> acid. Aldehyde also -> acid (Tollens conditions too). 2 alcohol stops at ketone. Interconversion map ties Ch18-21 synthesis.
Examples Ethanol -> ethanoic · Orange green · No 3 alcohol path
Exam Application
Exam hill: 1 alcohol -> aldehyde -> acid (ox) acid back to 1 alcohol needs a named strong reductant ketones do not become acids with Tollens
Examples Ethanol -> ethanoic · Orange green · No 3 alcohol path
WHAT — FROM ACID TO ALCOHOL AND BACK — OXIDISE UP
1 alcohol reflux dichromate -> acid. Aldehyde also -> acid (Tollens conditions too). 2 alcohol stops at ketone. Interconversion map ties Ch18-21 synthesis. This page separates the idea from the wider topic “FROM ACID TO ALCOHOL AND BACK” so it can be revised and assessed on its own.
WHY — Why this topic matters
FROM ACID TO ALCOHOL AND BACK — OXIDISE UP is an independent FBISE learning unit because students must use its definitions, conditions, equations, or trends separately in explanations and calculations.
HOW — How it works
1 alcohol reflux dichromate -> acid. Aldehyde also -> acid (Tollens conditions too). 2 alcohol stops at ketone. Interconversion map ties Ch18-21 synthesis. Examples: Ethanol -> ethanoic; Orange green; No 3 alcohol path. Exam use: Exam hill: 1 alcohol -> aldehyde -> acid (ox) acid back to 1 alcohol needs a named strong reductant ketones do not become acids with Tollens

Common misconception
- Do not treat oxidise up as the same as every other part of from acid to alcohol and back; define this unit and use its own evidence, steps, or conditions.
FBISE exam check
- Define from acid to alcohol and back — oxidise up, explain how it works, and support the answer with one relevant example.
60-second revision
