1. Shankar and Sameer performed an experiment to differentiate primary, secondary and tertiary amines in a laboratory. Shankar correctly identified those 3 compounds but Sameer could only identify primary amine. a) What may be the reagent used by Sameer 1) Ammonical Silvernitrate solution 2) Chloroform & Caustic potash 3) Aqueous Copper Sulphate solution

2) Chloroform & Caustic potash

Explanation:

The carbylamine reaction is a kind of chemical test which is done to detect primary amines in an unknown solution. It cannot detect secondary and tertiary amines.

The reaction involves the heating with up of the unknown solution with alcoholic potassium hydroxide or caustic potash and the chloroform.

In the presence of primary amine, the production of isocyanide results.

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of c is as shown here in the image.
