How many times primary alcohol oxidise
2
How many times does secondary alcohol oxidise
1
How many times does tertiary alcohol oxidise
These are not oxidised by aqueous acidified potassium dichromate
What does a ketone end in

What is the antibumping granules used for in distillation
To prevent superheating that leads to violent/explosive boiling
What can you do to get higher yield or carboxyilc acid
Heat under reflux to ensure any aldehyde made is conducted back into the oxidising agent. This promotes further oxidation of the aldehyde to get a higher yield of carboxylic acid
