Halogenoalkanes

Описание: This video covers Edexcel AS Chemistry Unit 2 (Application of Core Principles of Chemistry) section 2.10 (2) a-f

a. demonstrate an understanding of the nomenclature and corresponding structural, displayed and skeletal formulae for halogenoalkanes, including the distinction between primary, secondary and tertiary structures
b. interpret given data and observations comparing the reactions and reactivity of primary, secondary and tertiary compounds
c. carry out the preparation of an halogenoalkane from an alcohol and explain why a metal halide and concentrated sulfuric acid should not be used when making a bromoalkane or an iodoalkane
d describe the typical behaviour of halogenoalkanes. This will be limited to treatment with:
i aqueous alkali, eg KOH (aq)
ii alcoholic potassium hydroxide
iii water containing dissolved silver nitrate
iv alcoholic ammonia
e. discuss the uses of halogenoalkanes, eg as fire retardants and modern refrigerants.
