 Paraffins: 

  • Another name of alkanes.
  • Paraffin is made of two words. Parum - little and affins - affinity.
  • Thus paraffins virtually means something which is less reactive. 
  • At the same time, Alkanes contain strong single covalent bonds between them and hence are chemically inert under normal conditions. This is the reason why Alkanes are called paraffins.
