What is the general formula for secondary amines? (2021) 2021
  • Step 1: Understand that amines are compounds that contain nitrogen (N).
  • Step 2: Know that amines can be classified into primary, secondary, and tertiary amines based on how many carbon groups (R) are attached to the nitrogen.
  • Step 3: For secondary amines, there are two carbon groups attached to the nitrogen.
  • Step 4: Represent the carbon groups as 'R'. Since there are two groups, we write it as R2.
  • Step 5: Add 'NH' to represent the nitrogen atom and one hydrogen atom attached to it.
  • Step 6: Combine these parts to form the general formula: R2NH.
