polarity - What determines "polarizability" of an element?
2017年6月29日 · The polarisability is a measure of how an atom's electrons can be displaced from equilibrium by a nearby electric field. The polarisability is approximately inversely proportional to the ionisation energy (taken across periods in the periodic table); the easier it is to ionise the easier it is to alter the average electron's positions because ...
Difference between polarity and polarizability
2017年1月31日 · Polarisability refers to the degree to which the electron clouds in a molecule or atom can be influenced by an external electric field. Everything, polar or not, has a polarisability. Crudely (i.e. simplifying a lot) you can think of it as the degree to which electrons are held tightly in the atom or molecule.

boiling point - Polarisability of alkynes, alkenes and alkanes ...
2017年9月16日 · This makes perfect sense as polarisability is linked to the strength of intermolecular forces and the strength of such forces determines the boiling points of the substances in the liquid state. However, my point of contention is his explanation of how alkynes are more polarisable due to their more electron-dense triple bond and how alkanes are ...
Significance & applications of polarizability for nucleophiles
2018年1月23日 · It seems to me that both trends end up pointing the same best uncharged nucleophiles, that means, polarizability increases down the periodic table (bigger electron clouds have a better overlap in the Sn2 transition state) while basicity decreases (the electron density is more disperse around bigger atoms).
organic chemistry - How is charge density a useful measure of ...
2015年4月2日 · So far I've been looking at different polarising power and polarisability and how that affects a substance in whether it is a hard or soft acid/base, but I don't understand how charge density comes into play, and how we can use it to understand the characteristics.
Relationship between electric dipole moment and polarization?
2015年7月1日 · $$\\vec{p}_\\text{ind} = \\alpha \\vec{E}$$ The induced dipole moment is the polarizability times the electric field vector. $$\\vec{P}(\\omega) \\propto \\chi^{(1 ...

2020年7月12日 · The strength of this interaction depends on polarisability of non-polar molecule. As an example, let's take the following examples: As an example, let's take the following examples:
experimental chemistry - How are polarizabilities measured ...
2018年2月21日 · The polarizability of molecules determines how a molecule interacts with other molecules (intermolecular interactions and chemical reactions), how it interacts with electromagnetic radiation (optical properties), and how it …
Parallel between polarisability of donor atom and CFS strength
2020年8月2日 · Observing the strength of crystal field splitting by different ligands, can the following be considered?: Most of the members in the series are ligands where the donor atom is nitrogen, oxygen or ...
