Organic 2 Flashcards
(10 cards)
structural formula
shows how molecules are arranged
displayed formula
shows every atom and every bond
homologous series
a group of compounds with:
- same functional group
- similar chemical properties
- trend in physical properties
- same general formula
e.g. alkanes
functional group
reactive part of a compound, atom/s that provide compound with its chemical properties
isomer
molecules with same molecular formula but different structural/displayed formula
alkanes
saturated hydrocarbons
no carbon double bonds
CnH2n+2
will only react with bromine water in UV light
alkenes
unsaturated hydrocarbons
carbon double bonds
CnH2n
will always react with bromine water, will turn from orange to colourless
substitution reaction
something in original molecule is replaced with something else
addition reaction
something is added to the starting molecule, only 1 product formed
addition polymerisation
many monomers (alkenes) bond together to form a long chain polymer, the double bond opens, so it can bond to other molecules, only 1 product formed
