How to Identify Primary, Secondary & Tertiary Alcohols | USING OXIDATION REACTIONS!
In this video, we walk through a common A-level chemistry exam question: how to identify whether an unknown alcohol is primary, secondary, or tertiary using oxidation reactions and test reagents.
We break it down with three unknown samples – A, B and C – and guide you step by step through the process:
• Oxidation using acidified potassium dichromate
• Interpreting the orange to green colour change
• Distillation of oxidation products
• Identifying aldehydes and ketones using Tollen’s Reagent and Fehling’s Solution
• Recognising a silver mirror or brick red precipitate for confirmation
You’ll learn how to apply this practically and confidently solve similar questions in your exam.
Perfect for A-Level Chemistry, OCR, AQA, CIE and Edexcel students.
