CH2 Revision (Halogenoalkanes)

These flashcards should provide the basic information on topic 7.3 for the WJEC Chemistry board.

What is a halogenoalklane?
A homologous series in which one or more hydrogen atoms in an alkane has been replace by a halogen.
1 of 11
What is hydrolysis?
A reaction with water to produce a product.
2 of 11
What is a nucleophile?
A species with a lone pair of electrons that can be donated to an electron deficient centre.
3 of 11
What are CFC's?
Halogenoalkanes containing both fluorine and chlorine.
4 of 11
Chlorine + Ag+(aq) ions
White precipitate and dissolves in dilute ammonia.
5 of 11
Bromine + Ag+(aq) ions
Cream precipitate and dissolves in concentrated ammonia.
6 of 11
Iodine + Ag+(aq) ions
Yellow precipitate and doesn't dissolve in ammonia.
7 of 11
Solubility of halogenoalkanes?
Although they are polar, they do not contain an O-H or N-H group which can hydrogen bond with water molecules. They are therefore insoluble in water. They can be used for degreasing; chloro compounds are often used as these are the cheapest.
8 of 11
Boiling temperature of halogenoalkanes?
Halogenoalkanes have a boiling point very close to room temperature, gases can therefore be liquefied and liquids can be evaporated easily.
9 of 11
Uses of halogenoalkanes?
Fire extinguishers, Refrigerants, Propellants and Anesthetic (trichloromethane)
10 of 11
Environmental effects pf CFC's?
CFC's undergo radical chain reactions that deplete the ozone layer.
