23 Οκτ 2024 · Ammonia (NH3) là một hợp chất hóa học phổ biến được biết đến với dạng khí không màu, có mùi hăng mạnh. Công thức hóa học của nó là NH3, trong đó có một nguyên tử nitơ và ba nguyên tử hydro liên kết với nhau.
The Lewis structure of H 2 O indicates that there are four regions of high electron density around the oxygen atom: two lone pairs and two chemical bonds: We predict that these four regions are arranged in a tetrahedral fashion (Figure \(\PageIndex{6}\)), as indicated in Figure \(\PageIndex{9}\).
Properties. Liquid NH 3. Solid NH 3. Two visible states of NH 3. Ammonia is a colourless gas with a characteristically pungent smell. It is lighter than air, its density being 0.589 times that of air. It is easily liquefied due to the strong hydrogen bonding between molecules.

Ammonia lewis structure contains three sigma bonds and one lone pair on nitrogen atom. Therefore, there are total of four electrons regions. So, hybridization of center atom, nitrogen is sp3. Because there are four electrons regions, geometry is tetrahedral and shape is trigonal pyramidal.
NH3 Ammonia. Ammonia has 4 regions of electron density around the central nitrogen atom (3 bonds and one lone pair). These are arranged in a tetrahedral shape. The resulting molecular shape is trigonal pyramidal with H-N-H angles of 106.7°.
Chemical structure: This structure is also available as a 2d Mol file or as a computed 3d SD file. The 3d structure may be viewed using Java or Javascript. Isotopologues: Ammonia-d3. Other names: Ammonia gas; Nitro-Sil; Spirit of Hartshorn; NH3; Ammonia, anhydrous; Anhydrous ammonia; Aromatic Ammonia, Vaporole.
