what is the homologous series
a family of organic compounds with the same functional group
what does complete combustion. of the alkenes produce
carbon dioxide and water
how do alkenes react
addition reactions
what makes alkenes more reactive than alkanes
there double carbon bond
what do alkenes react with
the halogens
what happens when an alkene reacts with hydrogen
an alkane is formed
what happens when an alkene reacts with steam
alcohol is produced
what is the functional group of an alcohol
-OH
what is the functional group of carboxylic acids
-COOH
what is the functional group for an ester
-COO-
why are alcohols used for perfumes and mouthwash
many organic substances dissolve in alcohols
how is ethanol manufactured
fermentation in which yeast converts sugar into an aqueous solution of ethanol
what do alcohols produce when they are burnt
carbon dioxide and water
how can alcohols become carboxylic acids
be oxidised by chemical oxidising agents such as potassium dichromate.
what are the properties of carboxylic acids and why
a typical acids because they react to produce carbon dioxide
how are carboxylic acids different to other acids
they react with alcohols in the presence of an acid catalyst to produce esters
why are some esters used as flavourings
volatile compounds and have distinct smells such as pleasant fruity ones .
why are carboxylic acids weak acids
carbon dioxide is given off more slowly when they react with a metal carbonate compared with hydrochloric acid when ethanoic acid dissolves in water it doesnt ionise completely
