1. Balance each of the following redox reactions:

3-octanol + KMnO4 (basic solution)

1-octanol + Na2Cr2O7 (acidic solution)

cyclohexene + KMnO4 (hot, acidic solution)

2. Ethers left open to the air for extended periods can become explosive due to the formation of hydroperoxides. Write a free radical chain mechanism for the air oxidation (autoxidation) of diethyl ether, initiated by an arbitrary radical R. .

3. Write two complete mechanisms for the addition of ethanol to 1-methylcyclohexene oxide:

a) catalyzed by acid (HCl in ethanol)

b) catalyzed by base (NaOEt in ethanol)
