Structure of Amines

3.4K
The hybridized nitrogen atom in amines possesses a lone pair of electrons and is bound to three substituents with a bond angle of around 108°, which is less than the tetrahedral angle of 109.5°. However, the C–N–H bond angle is slightly larger at 112°, with a carbon–nitrogen bond length of 147 pm. This carbon–nitrogen bond length of of amines is longer than the carbon–oxygen bond of alcohols (143 pm) but shorter than alkanes’ carbon–carbon bond (154 pm). These aspects are...

Chirality at Nitrogen, Phosphorus, and Sulfur02:30

Chirality at Nitrogen, Phosphorus, and Sulfur

7.3K
Chirality is most prevalent in carbon-based tetrahedral compounds, but this important facet of molecular symmetry extends to sp3-hybridized nitrogen, phosphorus and sulfur centers, including trivalent molecules with lone pairs. Here, the lone pair behaves as a functional group in addition to the other three substituents to form an analogous tetrahedral center that can be chiral.
A consequence of chirality is the need for enantiomeric resolution. While this is theoretically possible for all...

Structure of Carboxylic Acid Derivatives
Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the unhybridized p...

Hybridization of Atomic Orbitals I03:24

Hybridization of Atomic Orbitals I

68.9K
The mathematical expression known as the wave function, ψ, contains information about each orbital and the wavelike properties of electrons in an isolated atom. When atoms are bound together in a molecule, the wave functions combine to produce new mathematical descriptions that have different shapes. This process of combining the wave functions for atomic orbitals is called hybridization and is mathematically accomplished by the linear combination of atomic orbitals. The new orbitals that...

¹H NMR of Conformationally Flexible Molecules: Temporal Resolution

1.4K
At room temperature, the chair conformer of cyclohexane undergoes rapid ring flipping between two equivalent chair conformers at a rate of approximately 105 times per second. These two chair conformers are in equilibrium. The rapid ring flipping results in the interconversion of the axial proton to an equatorial proton and an equatorial to the axial proton. Such interconversions are too rapid and cannot be detected on the NMR timescale. Hence, the NMR spectrometer cannot distinguish between the...

Area of Science:

  • Inorganic Chemistry
  • Theoretical Chemistry
  • Materials Science

Background:

  • Nitrogen typically adheres to the octet rule, with electron counts of eight in its valence shell.
  • Despite extensive research, hypervalent nitrogen compounds, featuring higher electron counts, have not been synthesized.
  • Nitrogen exhibits diverse oxidation states, ranging from +5 to -3.

Purpose of the Study:

  • To present theoretical evidence for the synthesis of hypervalent nitrogen compounds.
  • To explore the possibility of creating a hexacoordinated nitrogen(V) species.
  • To identify potential synthetic routes for novel nitrogen-containing materials.

Main Methods:

  • Computational chemistry methods were employed to investigate potential nitrogen hypervalency.
  • Theoretical calculations were performed to assess the stability of proposed nitrogen compounds.
  • High-pressure synthesis conditions were simulated to determine feasibility.

Main Results:

  • Theoretical evidence suggests the feasibility of synthesizing a salt containing hexacoordinated nitrogen(V) (NF6-).
  • This synthesis could be achieved at a pressure of 40 GPa through the oxidation of NF3 by F2.
  • The proposed compound satisfies the criteria for hypervalent nitrogen.

Conclusions:

  • The synthesis of hypervalent nitrogen compounds is attainable with current high-pressure experimental techniques.
  • This research opens avenues for a new class of nitrogen-containing materials.
  • The findings challenge the long-standing limitations of nitrogen's electron configuration.
