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...

Hypothesis vs Theory vs Law - Answer-Hypothesis: If, then, because Law: Statement or equation about a relationship - ex: force = mass * gravity Theory: Explains why a law exists Law of Conservation of Mass - Answer-Mass is always constant - Reactant mass = Product mass They are used (upheld) in chemical equations Three common states of matter and their characteristics - Answer-- Solid (s): color - Liquid (aq): melting point, solubility - Gas (g): Difference between Elements, Compounds,...
