Winter Final 2014 Q8B

Postby Miriam Velez 1I » Thu Mar 10, 2016 5:15 pm

On the Winter 2014 Final Q8B why is the aldehyde named butanal and not butenal? Is the double bond implied?

By definition, an aldehyde is R-(C=O)(H), with the H attached to the carbon. Thus, the double bond is implied. You would only do "enal" if there were another double bond in the parent chain.
