Answer 1

Answer:

primary and secondary can be distinguished by hinsberg test

Answer 2

Answer:

Primary and secondary amines are distinguished by nitrous acid HNO2

Explanation:

Amines are classified as primary and secondary, or tertiary according to the number of carbons bonded directly to the nitrogen atom. Primary amines have one of the carbon bonded to the nitrogen. Secondary amines have two carbons bonded to the nitrogen, and tertiary amines have three carbons bonded to the nitrogen.

Primary amines when they reacted with the nitrous acid forms alcohols and the secondary amines when they  reacted with nitrous acid forms N-nitroso derivative.

1 degree Amines :- R-NH2→ ^HNO2    R-N+≡ NX- →R +→R-OH (alcohol)

2 degree Amines :-R2-NH→^HNO2   R2-N-NO(N-Nitroso derivatives)
