meth- - CORRECT ANSWER - -1 carbon atom
eth- - CORRECT ANSWER - -2 carbon atoms
prop- - CORRECT ANSWER - -3 carbon atoms
but- - CORRECT ANSWER - -4 carbon atoms
flammable - CORRECT ANSWER - -capable of being easily set on fire;
combustible
viscosity - CORRECT ANSWER - -a measure of the resistance of a liquid to
flow
volatility - CORRECT ANSWER - -a measure of how readily a substance
vaporises
complete combustion - CORRECT ANSWER - -Excess oxygen is required,
and it produces CO₂(g) + H₂O(g).
incomplete combustion - CORRECT ANSWER - -Limited oxygen is
available, and it produces CO₂ (g) + CO(g) + C(s) + H₂O(g)
thermal decomposition - CORRECT ANSWER - -The breaking up of a
chemical substance by heating into at least two chemical substances.
, cracking - CORRECT ANSWER - -The process of breaking large
hydrocarbon molecules into smaller ones
alkene - CORRECT ANSWER - -A hydrocarbon containing one double bond
between two adjacent carbon atoms.
unsaturated hydrocarbon - CORRECT ANSWER - -A hydrocarbon containing
double and/or triple carbon-carbon bonds.
bromine water - CORRECT ANSWER - -Used to test for saturation, a
brown/orange solution that decolourises in the presence of an alkene.
C10 - CORRECT ANSWER - -
functional group - CORRECT ANSWER - -An atom or group of atoms that
confers specific properties on an organic molecule.
homologous series - CORRECT ANSWER - -A group of organic compounds
with related structures and properties; each successive member of the series
differs from the one before it by a specific number of carbon and hydrogen
atoms (usually CH₂).
alcohol - CORRECT ANSWER - -An organic compound containing a
hydroxyl (—OH) group.
carboxylic acid - CORRECT ANSWER - -an organic acid containing a
carboxyl group. The simplest examples are methanoic (or formic) acid and
ethanoic (or acetic) acid.
