18 Jul 2006, 4:26 PM | Hi, I could explain this here, or you could simply check out http://www.chemistrycoach.com.au/L3_tut.pdf read through that and see if it helps at all. They are just a bunch of question with solution. I'm sure someone will come along and answer this question for you, if not i might just post up a some notes on it. Best of luck. George p.s. this is a very important concept to learn, it is in your year 11 textbook. |

21 Jun 2006, 12:36 PM  | i don't think pentene is polar. if you're talking about polarity in relation to molecules, not bonding, then remember something about the symmetry of a molecule? if the charges cancel each other out then it's non-polar. or something  that was years ago '-_-
