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 a primary amine as it has one alkyl/aryl group and two hydrogens attached to nitrogen.
- Option B ($H_2NRNH_2$) is not a common amine formula representation.
- Option C ($RN_2H$) is not a typical amine formula.
