1. Which attractions are stronger: intermolecular or intramolecular?

2. How many times stronger is a covalent bond compared to a dipole-dipole attraction?

3. What evidence is there that nonpolar molecules attract each other?

4. Which chemical has the weakest intermolecular forces water or ammonia? Which has the

strongest? How can you tell?

5. Suggest some ways that the dipoles in London forces are different from the dipoles in dipole-dipole attractions.

6. A) Which would have a lower boiling point: O2 or F2? Explain. B) Which would have a lower

boiling point: NO or O2? Explain.

7. Which would you expect to have the higher melting point (or boiling point): C8H18 or C4H10? Explain.

8. What two factors causes hydrogen bonds to be so much stronger than typical dipole-dipole bonds?

9. Ethanol (CH3CH2OH) and dimethyl ether (CH3OCH3) have the same formula (C2H6O). Ethanol boils at 78 °C, whereas dimethyl ether boils at -24 °C. Explain why the boiling point of the ether is so much lower than the boiling point of ethanol.

I have been watching several fan poster of The Dark Knight Rises, many of them are like the caracter posters (the ones that originally had Bane, Batman or Catwoman and said RISE at the top) and I wanted to know where can I find the image on the background to make a poster like it but with another character, so can anyone tell me where can I get the background image?
