1. The aldol condensation reaction belongs to a group of reactions characterized by formation of an enolate. For each of the following aldehydes or ketones, draw the enolate ion that forms when treated with a strong base such as sodium hydroxide. If an enolate cannot form, put NR (no reaction). 2. The first step in the aldol addition of acetaldehyde is an acid base reaction (proton transfer). pka = 16 pka = 15 OH a. The pk, for each acid...

An three-dimensional structure of benzoin and the general reaction
mechanism o reductions. As shown previously (10-1), the usual mode
of activation tor reduction occurs via an intermolecular H-bond
between the carbonyl group and an a intramolecular H-bond can
stabilize the lowest-energy conformation of benzoin (pre and serve
to activate the carbonyl for reduction, thus generating the
lowest-energyt state. a) Draw the lowest-energy,...
