Oxidation of alcohols Flashcards
What are the two chemicals needed to make an oxidation agent?
Sodium dichromate (Na2Cr2O7) or potassium dichromate (K2Cr2O7) and dilute sulfuric acid
What is the observation for a successful oxidation?
Reaction mixture turns from orange to green/blue
How do you form an aldehyde?
Mild distillation with potassium dichromate and dilute sulfuric acid
What is the functional group of an aldehyde?
-CHO
How do you draw an aldehyde?
An oxygen double bonded to a carbon also with a H bonded
What does the oxidation of primary alcohols form?
An aldehyde or carboxylic acid
How do you form a carboxylic acid?
Heat under reflux with excess potassium dichromate solution and dilute sulfuric acid
What is the functional group of a carboxylic acid?
-COOH
How do you draw a carboxylic acid?
An oxygen double bonded and a single bonded OH to a carbon
What does oxidation of secondary alcohols form?
A ketone
How do you form a ketone?
Heat under reflux with excess potassium dichromate solution and dilute sulfuric acid
What is the functional group of a ketone?
-CO
How do you draw a ketone?
An oxygen double bonded to a carbon
What does the oxidation of a tertiary alcohol form?
Nothing
What is reflux?
When volatile reactants are heated for long
