Alkanes are saturated hydrocarbons (they do not have any double bonds and all the carbond bonds are attched to hydrogen atoms). The have the formula CnH2n+2 where n is a whole number. 

Alkenes are unsaturated hydrocarbons  (they have one carbon double bond where two carbons are bonded together).  They have the formula CnH2n where n is a whole number.

Have look at this as it explains alkanes and alkene very well with diagrams

(alkenes is on the next page)

Its says it is for OCR but I did AQA and it helped!

Hope that helps! :)
