organichelpmepls Posted April 20, 2014 Share Posted April 20, 2014 Indicated the hybridisation state of all the non-hydrogen atoms in the following molecules,CH3COCH2OCH3 and HCCCNi can't really seem to understand my chemistry teacher, and i really need to pass this coursework to get into university, all help is very much appreciated Link to comment Share on other sites More sharing options...
rktpro Posted April 21, 2014 Share Posted April 21, 2014 Hybridisation is not something which you can solve as a problem yourself and find it out. Try google or a good textbook to learn chemical bonding. In organic books, it is usually the first chapter. Link to comment Share on other sites More sharing options...
organichelpmepls Posted April 21, 2014 Author Share Posted April 21, 2014 Okay, how about this question, draw the structures of the products that you would obtain by treatment of benzaldehyde : a) MeMgCl, followed by H30+ b) NaBH4 Link to comment Share on other sites More sharing options...
Fuzzwood Posted April 21, 2014 Share Posted April 21, 2014 Read your course book. Clearly grignard and reduction agents must have been discussed. Link to comment Share on other sites More sharing options...
organichelpmepls Posted April 21, 2014 Author Share Posted April 21, 2014 I am doing a foundation course which is a mixture of a-levels and 1st year university chemistry, there is no textbook or coursework book, and i feel like I'm struggling with it. i've been googling and googling for hours, with no answers.

organichelpmepls Posted April 22, 2014 Author Share Posted April 22, 2014 alright i found for NaBH4, but no luck with MeMgCl and H3O+, anyone know the answer? Link to comment Share on other sites More sharing options...
organichelpmepls Posted April 23, 2014 Author Share Posted April 23, 2014 anyoneeeee Link to comment Share on other sites More sharing options...
Fuzzwood Posted April 23, 2014 Share Posted April 23, 2014 What happened after searching for those keywords I gave? Link to comment Share on other sites More sharing options...
rktpro Posted April 23, 2014 Share Posted April 23, 2014 Even if you solve 1000 problems by google search or asking someone, without reading theory, you wouldn't gain much. Try a good textbook, something like Morrison and Boyd and then tackle problems. Link to comment Share on other sites More sharing options...
organichelpmepls Posted April 23, 2014 Author Share Posted April 23, 2014 so basically benzaldehyde is a aldehyde and MeMgCl is a grignard agent? reading it off this website , http://www.organic-chemistry.org/namedreactions/grignard-reaction.shtm Link to comment Share on other sites More sharing options...
hypervalent_iodine Posted April 23, 2014 Share Posted April 23, 2014 so basically benzaldehyde is a aldehyde and MeMgCl is a grignard agent? reading it off this website , http://www.organic-chemistry.org/namedreactions/grignard-reaction.shtm Yes. I mean no offense by this, but if you didn't even know that benzaldehyde was an aldehyde then I think it would be in your best interest to read up on some basic organic chemistry before you start going through reactions.

organichelpmepls Posted April 23, 2014 Author Share Posted April 23, 2014 i did know that benzaldehyde was an aldehyde.. but i still can't figure out the product of it when treated with MeMgCl and H3O+ Link to comment Share on other sites More sharing options...
hypervalent_iodine Posted April 23, 2014 Share Posted April 23, 2014 Grignard reactions typically have an acid work up step if that's the part that's confusing you. The product will still be what you would expect from a Grignard reaction. Link to comment Share on other sites More sharing options...
Elite Engineer Posted April 23, 2014 Share Posted April 23, 2014 i did know that benzaldehyde was an aldehyde.. but i still can't figure out the product of it when treated with MeMgCl and H3O+ Grignard reagents in short produce carbanions, which you may or may not know are negatively charged or nucleophilic. The carbon on the aldehyde group is positive due to oxygen's high electronegativity; oxygen literally pulls electrons from carbon making it less negative and more positive or electrophilic. Now you have a positive carbon and a negative carbon...what do you think will happen when they interact? ~ee Link to comment Share on other sites More sharing options...
