Weird Nomenclature In Carbonyl Chemistry

Weird Nomenclature In Carbonyl Chemistry

March 26, 2012

Making it through the chemistry of carbonyl derivatives (ketones, aldehydes, carboxylic acids, esters, and more) there are at least two “weird” nomenclature issues that repeatedly come up to baffle student…

Reaction Friday: Formation of Acetals from Ketones

February 24, 2012

Today’s video is about the formation of acetals from aldehydes and ketones, an important method for the protection of the carbonyl group. One thing I forgot to mention in the video is that the reaction is an equ…

Oxidation Ladders

Oxidation Ladders

August 8, 2011

Once you get a handle on oxidations and reductions, you might start to notice that with some molecules these reactions can proceed in sequences. For example, if you start with an alkane with a CH3 group, the alkane ca…
