· In addition reactions, two or more
substances react to form a single product
· Reactant 1 + Reactant 2 = Single product
· Example: Bromine undergoes an addition
reaction with ethene to form 1,2
· An elimination reaction is an organic
reaction in which a small molecule is
removed from a larger molecule.
· This leaves a double bond in the larger
· For example the dehydration of ethanol.…read more
· A condensation reaction involves an
addition reaction followed by an elimination
· As a result, two reactants combine to form a
larger molecule, with the elimination of a
small molecule such as water or hydrogen
· As example is the formation of ester from
carboxylic acid and an alcohol, and water is
produced alongside the main product.…read more
· In a substitution reaction one atom or
group of atoms is replaced by another
atom or group of atoms.
· Reactant 1 + Reactant 2 => Product 1 +
· For example the substitution of chlorine
for hydrogen to an alkane in free radical
· Oxidation is the loss of electrons.
· Reduction is the gain of electrons.
· For example the oxidising agent
potassium dichromate when added to
alcohol. The orange dichromate ions
Cr2O72- is reduced to dark green
chromium ions Cr3+
· This is an example of a redox reaction.…read more
