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...

What are biodegradable plastics? - Ans .-Broken down by enzymes What are photodegradable plastics? - Ans .-Broken down by U.V. Light What is the general formula of alkanes? - Ans .CnH2n+2 Are alkanes saturated or unsaturated and why? - Ans .-Saturated -Each carbon atom forms four strong covalent, single, sigma bonds around it Are alkanes polar or non-polar and why and how does this affect their solubility and reactivity? - Ans .The electronegativities of carbon and hydrogen are very simila...
