organic chemistry Flashcards
general formula for both
alkanes = CnH2n+2 Alkenes = CnH2n
fractions meaning
a group of compounds with similar boiling points
saturated meaning
that their carbon atoms are joined to each other by single bonds
unsaturated meaning
that they have a double carbon bonds
kerosene
fuel for aircrafts
fuel oil
fuel for ships and power stations
bitumen
for road surfaces
diesel
fuel for some cars and trains
gasoline
fuel for cars
refinery gas
fuel for domestic cooking
members of haemoglobin series
trends in physical properties
the same general formula
similar chemical reactions
same functional groups
fuel meaning
realises energy when burnt
hydrocarbon
compound that only contains carbon and hydrogen bonds
complete combustions
hydrocarbon + oxygen - carbon dioxide + water
incomplete combustion equations
hydrocarbon + oxygen - carbon monoxide + water
crackling
crackling is the thermal catalytic decomposition of large alkanes one or more smaller alkenes and one alkane
long chain hydrocarbon
greater demand
greater supply
alkenes can be used to make polymers
how are fraction obtained
crude oil being heated and then passed over a catalyst and then the fraction are condensed into different higets
incomplete combustion dangers
co produced
is toxic
binds to haemoglobin preventing oxygen transport
is colourless and orderless so harder to detect
fraction distillation for crude oil
use a Liebig cindenser and thermometer. heat the crude oil then collect the liquids
