Amines and Amides: Naming, Boiling Points and Why Amines Are Bases | Year 12 Chemistry

Full lesson, notes and practice questions: https://hscscience.com.au/subjects/ch... Amines and amides both contain nitrogen, but only an amine turns red litmus blue. See how to classify amines as primary, secondary or tertiary, how to name amines and amides by IUPAC rules, why amines boil lower than alcohols while amides boil higher than carboxylic acids, why an amine's lone pair makes it a weak base, and why the C=O beside an amide's nitrogen leaves it close to neutral. Then compare an organic acid with an organic base, including the salt they form together.

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" "explain the properties within and between the homologous series of carboxylic acids amines and amides with reference to the intermolecular and intramolecular bonding present" "investigate the differences between an organic acid and organic base" This video covers amines and amides, and compares the organic base with the organic acid. Carboxylic acids have their own video. Official 2017 course: https://www.nsw.gov.au/education-and-... Prerequisite: Why are carboxylic acids acidic?
