I can imagine where iron and copper were used. But I have little idea about where zinc and lead were used.

For each pair of compounds examine the different types of strain present, then identify the more stable (lower energy) isomer or compound and explain your reasoning.

2.a) cyclopentane b) methylcyclobutane

Correct me if I'm wrong, but it evaporates more than water because water stores extra energy in it's bonds right? Is that the only reason? Then why does gasoline rise above air if it is such a big molecule? Does it? Okay, if it doesn't then why does Carbon Tetrachloride, which is obviously heavier than most air rise to the ozone to deplete it? I know dust rises because it is big and catches wind like a kite. Is it the same reasoning?
