what is the general formula for a secondary amine?\no rnh₂\no h₂nrnh₂\no rn₂h\no r₂nh

Answer

Answer:

D. $R_2NH$

Explanation:

Step1: Recall amine classification

Amines are classified based on the number of alkyl or aryl groups attached to the nitrogen atom.

Step2: Define secondary amine

A secondary amine has two alkyl or aryl groups ($R$) attached to the nitrogen atom and one hydrogen - atom attached to the nitrogen. So its general formula is $R_2NH$.

Step3: Analyze other options

  • Option A ($RNH_2$) is the general formula for a primary amine where one alkyl/aryl group is attached to nitrogen and two hydrogens are attached to nitrogen.
  • Option B ($H_2NRNH_2$) is not a common general formula for amines.
  • Option C ($RN_2H$) is not a correct general formula for amines.
