Question

What is the basis for classifying amines as primary, secondary, or tertiary?

• A. The number of carbon atoms bonded directly to the nitrogen atom
• B. The number of carbon atoms bonded to a carbon bearing nitrogen
• C. The number of nitrogen atoms present
• D. The number of hydrogen atoms present

Answer 1

The correct option is A The number of carbon atoms bonded directly to the nitrogen atom

Basic criteria for classifing amines as primary, secondary or tertiary is that chow much number of carbon atom bonded directly nitrogen atom.

If three carbon directly attached then $3^0$ amine

If two carbon directly attached then $2^0$ amine

If one carbon directly attached then $1^0$ amine
