Difference between carbonyl and acyl?
« on: May 07, 2008, 04:46:04 PM »
What is the difference?

Is a acyl chloride considered a carbonyl? Why or why not?

Is an ester, aldehyde, etc considered an acyl? Why or why not?

Thanks very much.

Acyl simply is notation for a certain functional group.

http://en.wikipedia.org/wiki/Acyl

An acyl chloride group is a carbonyl, it just has a chlorine attached to it.  Aldehydes are acyl groups with a hydrogen.  I suppose they could be called acyl hydrides, maybe?  But they're used so often, they referred to as an aldehyde.
