Year 12 Alcohols, Haloalkanes and Analysis Chemistry Key Definitions

?
Primary Alcohol
Has a functional group attached to a carbon atom with no more than one alkyl group
1 of 17
Secondary Alcohol
Has a functional group attached to a carbon atom with two alkyl groups
2 of 17
Tertiary Alcohol
Has a functional group attached to a carbon atom with three alkyl groups
3 of 17
Reflux
The constant boiling and condensing of a reaction mixture. This ensures that the reaction goes to completion as fully as possible without losing reactants or products as vapour to the air
4 of 17
Dehydration
A chemical reaction in which water molecules are are eliminated from an organic compound
5 of 17
Elimination
An organic reaction in which one reactant forms two products. Usually a small molecule like water is released
6 of 17
Primary Haloalkane
The halogen atom is on the end of the chain
7 of 17
Nucleophile
Electron pair donors. This means they are also Lewis bases. They have a partial or full negative charge eg. H2O, OH-, NH3
8 of 17
Nucleophilic substitution
A chemical reaction in which an atom or group of atoms is exchanged for a nucleophile
9 of 17
Hydrolysis
A nucleophilic substitution chemical reaction in which water is a reactant. There are alkali hydrolysis reactions where -OH- is the reacting species
10 of 17
Ozone Layer
An area of high concentration of ozone, O3, in the stratosphere
11 of 17
Radical
A highly reactive species with one or more unpaired electron
12 of 17
Chlolofluorocarbons (CFCs)
A class of inert organic compounds that contain chlroine atoms and flourine atoms
13 of 17
Distillation
Technique used to separate miscible liquids or solutions
14 of 17
Separating funnel
A piece of equipment used to separate immiscible liquids
15 of 17
Redistillation
The purification of a liquid using multiple distillations
16 of 17
Molecular Ion, M+
The positive ion formed in mass spectrometry when a molecule loses an electron. Its Mr is equal to the Mr of the compound as the mass of the lost electron is negligible
