Ketones, in general, are less susceptible to nucleophilic attack than aldehydes, so in a reaction mixture containing both an aldehyde and a ketone, the aldehyde will react faster with nucleophiles thus, it is possible to perform a crossed aldol reaction in which the enolate formed by abstraction of the alpha-hydrogen on the ketone attacks .
