Double bond
what are single carbon to carbon bonds called?
saturated
what are carbon to carbon double bond called?
unsaturated
what happens to the bp as the molecular gets bigger in size?
increases, main force of attraction between hydrocarbons is LDF so the LDF between bigger molecules is stronger
what are the main force of attraction of hydrocarbons?
LDF
why does it take more energy to break apart the intermolecular forces between big molecules than smaller molecules?
bigger molecules have more electrons than smaller molecules therefore have more LDF intramolecular forces to break
what does volatility mean?
evaporate
why do smaller molecules evaporate more easily than larger?
less electrons so they have less LDF intramolecular forces
how to break a double bond
addition reaction
why is bromine solution used to find unsaturation?
decolourises bromine solution quickly
what are isomers
compounds with the same molecular formula but different structural formula
why can hydrocarbons not dissolve in water?
as non polar can’t dissolve in polar as it can’t form hydrogen bonding
