1. Topic: Function Group #4-Ketones Do Now: In terms of IMF, explain the difference in boiling point

2. General Format: R and R' may or may not be the same (but have to be carbons/carbon chains) Carbonyl group: within located within C chain R  C  R' = O C = O

3. Properties Carboxyl group makes ketone molecules polar = soluble in water Dipole-Dipole interactions –Boiling point: higher than alkanes (same # C’s) lower than alcohols (same # C’s)

4. Have you ever smelled a ketone?! Camphor

5. one Naming Ketones Must use number to indicate location of carboxyl group – use lowest possible number Take corresponding alkane name: – Drop -e & add -one

6. 2-propanone Common name = acetone 2-pentanone
