What is NF3?
NF3是氮三氟化物。它的通用名称是三氟胺。它具有三个通过共价化学键合与相同氮原子结合的氟原子。由于氮具有五个价电子,而三个氟原子仅使用其中三个电子来建立化学键,因此氮原子上有一个孤独的电子对。电子对和三个共价键使NF3分子具有三角锥体几何形状。结构如下:
The molar mass of nitrogen trifluoride is 71 g/mol. It appears as a colourless gas, and it has a mouldy odour. Furthermore, it is a non-flammable gas. However, this gas is a strong greenhouse gas. At the presence of electric discharges, we can prepare this compound using its chemical elements; thus, it is a rare compound we can prepare directly using its chemical elements (nitrogen and fluorine atoms).
Besides, this compound shows significant solubility in water. Furthermore, nitrogen trifluoride is nonbasic, and it has a low dipole moment because the fluorine atoms act as electron-withdrawing groups; thus, they can attract the lone electron pair on the nitrogen atom. Also, this compound is a potent oxidizer as well. When considering the uses of this compound, it is useful in plasma etching of silicon wafers in electrochemical applications.
What is NH3?
NH3 is ammonia. It has three hydrogen atoms bound to the same nitrogen atom. Like nitrogen trifluoride, this compound also has a lone electron pair. It is a binary halide. Furthermore, this compound occurs as a colourless gas, and it has a pungent, irritating odour. The geometry of this compound is trigonal pyramidal.
The molar mass of ammonia is 17 g/mol. In nature, we can find this gas as a trace compound formed from nitrogenous waste and nitrogenous animal and plant matter. When considering its uses, about 88% of ammonia is used for fertilizer production. It is also useful as a precursor for nitrogenous compounds. In fermentation processes, ammonia is useful as a nitrogen source for microorganisms. Aqueous ammonia is also important as a cleaner in household applications.
What are the Similarities Between NF3 and NH3?
- NF3 and NH3 are binary compounds.
- They have the same geometry – trigonal pyramidal
- 此外,两者都以无色气体的形式出现
- In addition to these, both molecules have lone electron pairs on nitrogen atoms.
What is the Difference Between NF3 and NH3?
NF3是氮三氟化物,而NH3是氨。NF3和NH3之间的主要区别在于,NF3包含三个与中央氮原子结合的氟原子,而NH3包含三个氢原子结合到中央氮原子。The molar mass of nitrogen trifluoride is 71 g/mol while the molar mass of ammonia it is 17 g/mol. Moreover, NF3 is nonbasic while NH3 is a basic compound; NF3 has a low dipole moment, but NH3 has a high dipole moment. NF3 is mainly useful in plasma etching of silicon wafers in electrochemical applications. In contrast, NH3 is useful for fertilizer production, for fermentation as the nitrogen source, as a cleaner in household applications, etc.
