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
