what are alkanes, the formula and the first 4
they are the simplest form of hydrocarbon and the formula is CnH2n+2. the first 4 are methane, ethane, propane, butane
what are hydrocarbon properties
increasing boiling points as the chain gets longer, more viscous the longer the chain, more flammable the shorter the flame
what is the equation for complete combustion
hydrocarbon+oxygen=carbon dioxide and water
what different products come out of the fractional distillation collum at each point
from bottom to top, bitumen, heavy fuel, diesel oil, kerosene, petrol, liquefied petroleum gas
what is cracking, what does it produce, what are the different methods
it splits up large hydrocarbons, it produces alkenes, you can split them using catalyst and heat or steam and heat
what’s the difference between an alkene and an alkane and how do you test for alkenes
alkenes have a double carbon bond alkanes have a single, you test for it using bromine water, it starts of orange but if you add an alkene and shake it it will turn colourless
