Read: pg. 240-242, 245 (sect. 10.4) - 246 (review of acids and bases)

pg. 446-456 and 439-444

HW: pg. 458-460 (7,8,9,11,13c,14b,17b,19b,28,32,33,37,38,45)

If carbon compounds are the basis of life, then

nitrogen compounds are the bases of life.

Objectives:

Know that amines are bases: They will form basic solutions in water (pH >7) and will form salts when combined with an acid.
Write a chemical equation for neutralization between and acid and a base.
Draw the conversion between a free base and its hydrochloride salt.
Write a chemical equation showing condensation of a carboxylic acid and amine yielding an amide; and hydrolysis of an amide yielding an amine and carboxylic acid.
Know that amino acids condense to form polyamide polymers (proteins).
Be able to draw amide and amine functional groups.
Be able to name simple and substituted amides

imagine the parent carboxylic acid, drop the "oic acid" and add "amide"
For a substituted amide begin with N- then name the substituted group

Be able to name amines: name the substituent groups and add amine.
Draw structures of purine and pyrimidine.
