EXPERIMENT NO. .
Aim: To deteet the presence of an aromatic primary amine in the given
organic compound.
EXPERIMENT OBSERVATION INFERENCE
Solubility Test:
Take I mL of the organic
compoundOrganc compound
in a cean test tube ard add to it
Aminc may be
1-2 dissolves. prcsenl.
ml ofdil HCI and shake well
Carbylamine test CNJ9:)
Take about 1 mb of the organic
compound and add to it i ml of
An ofensive smel of Aiphatic or aromatiIc
2. chloroform and 2-3 mL of 10%
carbylámine is produced. 1°amine present
alcohoicpotassium hydroxide
solution. Mix well and warm the
solution gently and smel carefuly
Azo dye test:
Dissolve 0.2 mL of the organic
compound in 2 mL of dil. HCl and
cool in ice to 0-5° C. Now add 2 ml .
Abrillant-orange or red Pnmary aromaluc
