NiCKEL Posted February 6, 2016 Report Share Posted February 6, 2016 I have the IB Chemistry questionbank and I've done in-book questions but where can I practice organics beyond those? Since the 2016 curriculum has a lot of differences with 2009 the questionbank doesn't help much, and I can't find any 2013+ past exams. Where is a good place to go for practice Reply Link to post Share on other sites More sharing options...
kw0573 Posted February 6, 2016 Report Share Posted February 6, 2016 Do all organic questions twiceEven if you are able to find 2009 through 2013, that's still 15 (3 timezones * 5 years) of paper 1, 15 of paper 2, 15 of paper 3 Organic Chem option G.There are also old university organic chemistry textbooks available online.

NiCKEL Posted February 6, 2016 Author Report Share Posted February 6, 2016 Ok thanks. In order to save space, a quick question: is it only nulceophiles that can attck electrophiles or can one attack the other? I remember being told to always from the arrow stemming from the nucleophile pointing to the electrophile so it feels weird saying the electrophile is attacking the nucleophile Reply Link to post Share on other sites More sharing options...
kw0573 Posted February 6, 2016 Report Share Posted February 6, 2016 "Attacking" is just a terminology. The real chemistry lies behind the curvy arrows, which represent the movement of electron pairs. We have the nucleophile that are willing to give away electrons (lewis base) and electrophiles that wants these electrons (lewis acids). Essentially we just have organic acid base (and on some cases, redox) reactions. Both species are attacking the other, per se. Reply Link to post Share on other sites More sharing options...
