Aldehydes and Ketones: Naming, Properties and Tollens' and Fehling's Tests | Year 12 Chemistry

Full lesson, notes and practice questions: https://hscscience.com.au/subjects/ch... Propanal and propanone have the same formula, C₃H₆O, yet only one turns a test tube into a silver mirror. See where the carbonyl group sits in an aldehyde and a ketone, how to name both by IUPAC rules, why their boiling points sit between alkanes and alcohols, and why Tollens' reagent, Fehling's solution and acidified dichromate react with aldehydes but not ketones. Then use a test to identify the product of an alcohol oxidation.

Syllabus dotpoints (NSW Chemistry Stage 6, 2017, Module 7): "investigate the nomenclature of organic chemicals, up to C8, using IUPAC conventions, including simple methyl and ethyl branched chains, including: (ACSCH127) alkanes alkenes alkynes alcohols (primary, secondary and tertiary) aldehydes and ketones carboxylic acids amines and amides halogenated organic compounds" "investigate the structural formulae, properties and functional group including: primary, secondary and tertiary alcohols aldehydes and ketones (ACSCH127) amines and amides carboxylic acids" "investigate the products of the oxidation of primary and secondary alcohols" This video covers naming, structure and properties for aldehydes and ketones. The other families are in their own videos. Official 2017 course: https://www.nsw.gov.au/education-and-... Prerequisite: Where can an alcohol reaction lead?
