what is the alkane formula ?
C n H 2n+2
what does homologous series mean ?
in a series where they can all be represented by the same formula
complete combustion equation
alkane + oxygen —> carbon dioxide + water (+energy)
what is incomplete combustion ?
when hydrocarbons burn without enough oxygen
not safe as carbon monoxide produced
smoky yellow flame and less energy
incomplete combustion equation
alkane + oxygen —> carbon + carbon monoxide + carbon dioxide + water (+energy)
how do haloalkanes form ?
when halogens react with alkanes under UV light
hydrogen atom substituted with halogen
difference between alkane and alkene
alkenes have C=C bonds
how do haloalkenes form ?
when halogens react with alkenes
addition reaction because C=C is split and halogen added to each carbon
how to test for C=C double bonds ?
add bromide water (orange) to alkene
SHAKE
if goes colourless, then there was C=C bond
(because dibromoalkalane is colourless)
add ethanoil
calm
what is a hydrocarbon ?
molecule made up of carbon and hydrogen atoms ONLY
what does biodegradable mean ?
breaks down by decomposers
