lnockohldo Posted July 13, 2012 Share Posted July 13, 2012 I am supposed to make notes explaining the exact mechanisms for these tests: Molisch's test, Anthrone test, Benedict's test, Barfoed's test, Bial's orcinol test, Seliwanoff's test, Osazone test All I could find are sh***y notes from my seniors who can't even spell 'Molisch'. All their structure diagrams are, to put is mildly, retarded (some carbons have 5 bonds etc.). Please help me find the exact structures of the reagents involved, the exact mechanism of the reaction, what's the test for etc. Link to comment Share on other sites More sharing options...
hypervalent_iodine Posted July 13, 2012 Share Posted July 13, 2012 ! Moderator Note Moved to homework. Inockohldo, we don't give answers here but we are willing to help you out if you're struggling to figure out concepts, etc. I have to ask if you actually bothered Googling any of those tests? Honestly, you could get your answers in 5 minutes if you had. Link to comment Share on other sites More sharing options...

hypervalent_iodine Posted July 13, 2012 Share Posted July 13, 2012 Alright, well you need to help us out here and tell us what specifically you're not getting about the mechanisms. Link to comment Share on other sites More sharing options...
lnockohldo Posted July 13, 2012 Author Share Posted July 13, 2012 (edited) OK, what's going on here? http://en.wikipedia.org/wiki/File:Molisch_test.png Edited July 13, 2012 by lnockohldo Link to comment Share on other sites More sharing options...
hypervalent_iodine Posted July 13, 2012 Share Posted July 13, 2012 What do you think? What level organic chemistry have you studied up to? Link to comment Share on other sites More sharing options...
lnockohldo Posted July 13, 2012 Author Share Posted July 13, 2012 What do you think? What level organic chemistry have you studied up to? I think I can visualize what is happening in the second row... (somewhat) The reaction form D-Glucose to 5-(hydroxymethyl)furfurol beats me. Well, I studied very basic organic chemistry.. only common functional groups, their nomenclature, isomerism etc. And that was a few years ago.. I had switched to physical sciences for 3 years and now I switched back to life sciences (this is from my biochemistry course). Link to comment Share on other sites More sharing options...
