For 10 points, aldehydes and ketones contain what functional group, which is a carbon-oxygen double bond?
The diastereoselectivity resulting when a nucleophile reacts with this functional group can be modelled via steric and inductive effects given that the nucleophile approaches this functional group at about 105 degrees; that model is the FelkinÂ–Anh model, which utilizes the BurgiÂ–Dunitz angle. Maleic anhydride is a great dienophile because it possesses two of these highly-electron withdrawing functional groups. They're not imines, but acid catalysts (*) "activate" this functional group by causing its central carbon atom to have a partial positive charge due to resonance. Grignard ("green-YARR") reagents reduce this general class of compounds to form either primary or secondary alcohols.
