What is the melting and boiling points of alkanes like? - ANSWER--as chain length 
increases so does the strength of the intermolecular forces as there is greater 
surface area for contact between molecules and hence stronger london forces 
and therefore the melting/boiling points are highr for longer chain. 
What is a structura/chain isomer? - ANSWER--Same molecular formula but a 
different structural formula
