This video lecture from Aldehydes and Ketones (F.Sc. second year Chemistry) covers Aldol Condensation. This is a condensation reaction where an alpha hydrogen containing carbonyl compound (being more acidic as discussed in last lecture) donates a proton to a base, becoming a nucleophile which acts another substrate molecule (a carbonyl compound) at the electrophilic carbon site. The pi bond shifts to oxygen giving an alkoxide ion which later abstracts a proton from water to give an Aldol. Find more e-learning material and educational video lectures in Urdu at maktab.pk.
