Aldol Condensation
« on: January 19, 2013, 10:11:06 AM »
Hi...I have a problem on aldol condensation. The question was to do a successful aldol condensation on "2-methyl pentanal". I did the "aldol" part, as shown in the attachment. But I'm struggling with the "condensation" part, where I have to remove a molecule of water. I know that the -OH has to be removed, but I don't know where the other hydrogen has to be removed from.

Thanks

There is a possibility in your molecule to eliminate water, look hard enough and you will see.

Do you remove the hydrogen from the carbon on the left of the carbon holding the -OH?
So in that case I'll get the following compound.....is that right?

CCCC(C)C=O>>CCCC(C)C(O)C(C)(C=O)CCC

CCCC(C)C(O)C(C)(C=O)CCC>>CCCC(C)=CC(C)(C=O)CCC

As far as I can tell, without breaking my neck, yes, that is the aldol condensation product.
Please put your pictures in a readable form, i.e. for English speaking from left to right.
For Australians upside down, etc.

I read the that the words "help" or the like were replaced by the "delete me" by the God of Fora who is all seeing and powerful.
