Base in Aqueous Solution
Triethylamine, sometimes known as Et3N, is a chemical molecule having the formula N(CH2CH3)3. Tetraethylammonium is also referred to as TEA, although it is important to use this abbreviation correctly to avoid misunderstanding with triethanolamine or tetraethylammonium, for which TEA is also a frequent acronym. It is a colourless volatile liquid with a pungent, ammonia-like fishy stench. Similar to Hünig's base (diisopropylethylamine), triethylamine is frequently used in chemical synthesis, typically as a base.
With the formula NH3, ammonia is a nitrogen and hydrogen inorganic chemical. Ammonia, the simplest pnictogen hydride and a stable binary hydride, is a colourless gas with a strong, pungent odour. It contributes considerably to the nutritional demands of terrestrial creatures by serving as a precursor to 45 percent of the world's food and fertilisers. Biologically, it is a common nitrogenous waste, especially among aquatic animals. About 70% of ammonia is used to create fertilisers, including urea and diammonium phosphate, in a variety of shapes and compositions. Additionally, pure ammonia is sprayed straight onto the ground.
The chemical formula for ethanamine, sometimes referred to as ethylamine, is CH3CH2NH2. It smells strongly of ammonia and is colourless. It turns into a liquid at a temperature just below room temperature that is soluble in almost all solvents. As is customary for amines, it is a nucleophilic base. In the chemical industry and organic synthesis, ethanolamine is frequently utilised.
Which of the following is the strongest base in an aqueous solution? (a) Triethylamine (b) Ammonia (c) Ethylamine (d) Diethylamine
The strongest base in an aqueous solution is diethylamine. It is more basic than triethylamine because triethylamine has steric hindrance, which makes it less basic.
