Carbonyl Compounds
Sec 1 Structure Properties Nature of the Carbonyl Group Carbon is sp2 hybridized. C=O bond is shorter,stronger, and more polar than C=C bond in alkenes. The carbonyl group is planar with bond angles of 120 length energy ketone C=O bond 1.23A 745 kJ/mol (178 kcal/mol alkene C=C bond 1.34A 611 kJ/mol (146 kcal/mol) Copyright 2005 Pearson Prentice Hall,Inc
