Alkanes AS Chemistry

HideShow resource information


they are saturated hydrocarbons which come in varying lengths and sizes 

the higher the number of carbons in the chain , the higher the boiling point this is because more weak inter molecular forces holding the individual molecules together . The greater the about of branching on the Alkane the lower the boiling point this is because the molecules can not pack as closely as a bunch of regularly shaped Alkane would.

The Alkanes are a homologous group/ series which means that they vary by the same thing each time , in this case CH2 when you add another carbon to the chain .Their general formula is CnH2n+2

that's all good and well but ... how do you name them ??

1. find the longest chain , you can go round corners but you can not go back on yourself  when working this out

you use this as the…
