.
saponification
base hydrolysis of ester yeilds carboxylate salt+alcohol
polymers
large molecule formed from many smaller repeatingu nits or monomers
esterification
alcohol and organic acid yield ester and water
amide hydrolysis requires:
strong aqueous acid and heat
sn1 ester hydrolysis reactants/reagents

Carbonyl Alpha Carbon Reactions Equlibrium Process Tautomerism
Reac: R-CH2-C=O-R ketotautomer Reag: Acid or Base Product: R-CH=C-OH-R enol tautomer
hydrogenation of an aldehyde
will produce RCHOH..which is a primary Alcohol

produces 2 alcohols
ester hydrolysis reactants/reagents
ester, water, base
Products of Combustion
CO2 + H2O
addition
unsaturated hydrocarbon and H or halogen yields halocarbon or alkaline
substitution
replacement of hydrogen in saturated hydrocarbons
ex. halogen solution
Ester + Carboxylic Acid
Acid Anhydride + ROH

Reac: EtO-C=O-C-C=O-OEt Reag: NaOEt, EtOH, H+/H2O, Delta T, R-X Product: R-COOH
R-OH + Cr2O72- (Then distilled off)
Primary Alcohol
R-CHO
Aldehyde Turns Orange to Green (dichromate)
LiAlH4 then H2O on epoxide
transforms to an alcohol with an SN2 mechanism
H attacks less substituted side
