AMIDES & AMINES. Introduction So far, we’ve dealt with compounds containing C, H, and O atoms. Many naturally produced compounds also contain nitrogen.

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+

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

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

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

Ethanamide vs Ethanoic Acid Propanamide
