Aldol condensation, Hydroxyl/alcohol group
« on: April 10, 2014, 12:47:14 PM »
Hi,

In the second part of my aldol condensation reaction we add water to the O- on the carbonyl group.

The end product is 3-hydroxybutanal,

Why is this not an alcohol? does the aldehyde take precedent? from first impressions and after googleing I cant see difference between hydroxyl group and alcohol from hydration

Regards

OK I hope I have answered my own question

all alcohols contain hydroxyl groups
not all molecules containing hydroxyl groups are alcohols

I just recently learned it too. You would probably learn it later as well.

But this is not the case here. The compound was 2-Hydroxybutanal.
