Re: ketonethnk u so much for making it so simple and easy to understand. friendship is tan 90°. #4 20131027 16:42:50

Re: ketoneNow, I would love to have someone explaining me Ester 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: ketoneAren't they just a combinations of an alchohol and a carboxilyc acid?

Re: ketoneYep, and they smell good too. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #9 20131119 07:18:26
Re: ketoneYeah. As far as I remember, they give fruit its smell.

Re: ketoneNote to Agnishom: To get esters, just take H from the OH group of the carboxilyc acid and the whole OH group from the alchohol and join the remainders together. You will also get water as a product.

Re: ketone
Yes, can you draw the functional group of the esters? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: ketoneSorry, Are you talking about this http://en.wikipedia.org/wiki/Ether ? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: ketoneyes i was talking about ether and now i got the answer. friendship is tan 90°.
