WebOct 26, 2024 · Triethylamine has three ethyl groups bonded to it, so that is the correct answer. Ammonia is , so it has no organic groups attached. Piperidine is a six-membered ring with a nitrogen as one of the members, making it a secondary amine. What is the difference between triethylamine and triethanolamine? Triethanolamine, or TEA, is an organic compound with the chemical formula N(CH2CH2OH)3. It is a colourless viscous liquid. It is both a tertiary amine and a triol. A triol is a molecule with three alcohol groups. Approximately 150,000 tonnes were produced in 1999. It is a colourless compound although samples may appear yellow because of impurities.
