(testing for alkene and alkane, charecterrisitc, chemical reaction) -…
testing for alkene and alkane
they both colourless
mix with bromine and solvent
alkene
when adding bromine into alkene to will be form dibromoalkene
bromine with solvent will turn yellow/ orange adding alkene will turn the colour of liquid to colourless
alkane
alkane is already staured therefor there is no space for bromine
charecterrisitc
alkene
double covalent bond
2 carbon
CnH2n
Unsaturated hydrocarbons
alkane
single covalent bond
follow alkane formula (CnH2n+2)
saturated hydrocarbons
chemical reaction
alkanes
CH4 + 2O2 → 2H2O + CO2
2C2H6 + 5O2 → 6H2O + 4CO2
