Polarization of the Carbonyl Group
-- Carbonyl group:
-- The oxygen has two lone pairs
-- The oxygen is more electronegative than the carbon
-- The polarization arrow will show electrons being pulled toward the oxygen
-- The carbon is partially positive
-- Partially positive = δ+
-- The oxygen is partially negative
-- Partially negative = δ-
-- These symbols go by the arrow
-- The polarization makes the boiling points of aldehydes and ketones higher than hydrocarbons
-- The larger the carbonyl group, the less soluble it is in water
-- If it has more than six carbons, it is insoluble
