OCR A LEVEL ORGANIC CHEMISTRY YEAR 12 WITH VERIFIED QUESTIONS AND ANSWERS 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 Wh...
