OK, this isnt really anything to do with mind altering substance chemistry, but is more of a query.
I have been given a chemical which is either an
Ester
Carboxylic acid
Alcohol
Phenol
Aldehyde
Ketone
Many people have suggested infra red, but unfortunatly we do not have the facilities in our school, i just need some ideas for basic chemical tests.
I would be most thankful if you help,
