1. Grp # 9: Amides
Do Now: Draw water molecules with correct orientation around this Na+ ion (hint: O end is negative and H end is postive) H+ H+ O- H+ H+ O-
Na+ O- H+ H+ O- H+ H+

2. carboxylic acid: RCOOH
General Format:
carbonyl group (C=O)
AND
amino group (NH2)
carboxylic acid: RCOOH
replace the OH with NH2
name: no # needed
Amide group is always at end of molecule
– just like _______________________
Carboxylic Acid and Aldehyde

3. Properties of Amides hydrogen bonding - so high bp
Simple amides are solids at room temp
Smaller amides are very soluble in water

4. Naming Amides Find name alkane with same # of C’s
drop the final -e & replace it with -amide

5. Ethanamide vs
Ethanoic Acid
Propanamide
