Title: Question About Ethanoic acid and Ethanal
Post by: karambinu on August 01, 2005, 10:02:50 AM

The question is as follows: Ethanal and ethanoic acid both contain carbonyl groups but while ethanal undergoes addition reactions as expected from a carbonyl group , ethanoic acid does not. Why?

Do bonds and electronegativities play an important role in answering such a question?

That's a really really really vague hint, geodome.
