Cycloaddition Reactions: MO Requirements for Thermal Activation01:16

Cycloaddition Reactions: MO Requirements for Thermal Activation

3.6K
Thermal cycloadditions are reactions where the source of activation energy needed to initiate the reaction is provided in the form of heat. A typical example of a thermally-allowed cycloaddition is the Diels–Alder reaction, which is a [4 + 2] cycloaddition. In contrast, a [2 + 2] cycloaddition is thermally forbidden.

Predicting Reaction Outcomes

8.4K
Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

Boundary Layer Characteristics01:18

Boundary Layer Characteristics

130
When a fluid encounters a solid surface, a boundary layer forms due to the interaction between the fluid's motion and the stationary surface. This phenomenon is characterized by a thin region adjacent to the surface where viscous forces dominate, influencing the fluid's velocity profile. The development of the boundary layer begins at the leading edge of the surface and evolves as the fluid moves downstream.As the fluid flows over the surface, friction between the fluid and the wall slows down...

Noncovalent Attractions in Biomolecules02:35

Noncovalent Attractions in Biomolecules

51.2K
Noncovalent attractions are associations within and between molecules that influence the shape and structural stability of complexes. These interactions differ from covalent bonding in that they do not involve sharing of electrons.
Four types of noncovalent interactions are hydrogen bonds, van der Waals forces, ionic bonds, and hydrophobic interactions.
Hydrogen bonding results from the electrostatic attraction of a hydrogen atom covalently bonded to a strong-electronegative atom like oxygen,...

Radical Reactivity: Overview01:11

Radical Reactivity: Overview

2.1K
Radicals, the highly reactive species, gain stability by undergoing three different reactions. The first reaction involves a radical-radical coupling, in which a radical combines with another radical, forming a spin‐paired molecule. The second reaction is between a radical and a spin‐paired molecule, generating a new radical and a new spin‐paired molecule. The third reaction is radical decomposition in a unimolecular reaction, forming a new radical and a spin‐paired...

Electrophilic Addition of HX to 1,3-Butadiene: Thermodynamic vs Kinetic Control01:23

Electrophilic Addition of HX to 1,3-Butadiene: Thermodynamic vs Kinetic Control

2.6K
The addition of a hydrogen halide to 1,3-butadiene gives a mixture of 1,2- and 1,4-adducts. Since more substituted alkenes are more stable, the 1,4-adduct is expected to be the major product. However, the product distribution is strongly influenced by temperature; low temperature favors the 1,2-adduct, whereas the 1,4-adduct is predominant at high temperature.

Area of Science:

  • Chemical reaction-diffusion systems
  • Fluid dynamics
  • Pattern formation

Background:

  • Boundary-bound reactions and chemical fluxes are crucial for pattern formation.
  • Turing instabilities and Rayleigh-Bénard convection are known phenomena in chemical and fluid systems, respectively.

Purpose of the Study:

  • To investigate chemical pattern formation in a fluid between reactive plates.
  • To explore the influence of chemical patterns on convective cell formation.
  • To establish a mechanism for controlling chemical and hydrodynamic instabilities.

Main Methods:

  • Modeling chemically reactive plates as chemical fluxes.
  • Analyzing a generic class of reaction-diffusion models.
  • Investigating two examples derived from the Schnakenberg-Selkov reaction.

Main Results:

  • Demonstrated chemical instabilities analogous to diffusion-driven Turing instabilities.
  • Observed hydrodynamic phenomena similar to Rayleigh-Bénard convection.
  • Identified chemohydrodynamic instability emerging from uniform density states, unlike classical Rayleigh-Bénard instability.
  • Found that convective cell formation is possible regardless of gravity's direction relative to the reactive plate.
  • Showed that device orientation influences cell wave number and flow direction.

Conclusions:

  • Chemical fluxes at boundaries can control pattern formation and convection.
  • Tuning reaction parameters offers a method to drive and alter fluid flow without mechanical pumps.
  • This work presents a novel approach to chemohydrodynamic control and pattern generation.
