Questions tagged [polarity]

For questions about polar or non-polar chemical species, or their comparison. Also, for questions where polar or non-polar solvents have an effect.

Polarity is the separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multipole moment.

What determines "polarizability" of an element?

In this question, the answer given discusses that fluorine has a good orbital overlap with hydrogen and also that fluorine is not very polarizable. However, is it always true that strong bonding is inversely related to polarizability?

Why doesn't silica gel dissolve in ethyl acetate

Why doesn't silica gel dissolve in ethyl acetate when something like aspirin does. Both silica gel and ethyl acetate are highly polar. I though like dissolved like.

Why does a molecule with a Thiol group form Hydrogen bonds?

I'm doing the GRE Biology practice test, and question #1 asks: The answer is E. I understand why II and IV are polar, but why is $\ce{R-S-H}$ polar? R is a side chain to the sulfur, sulfur's valence shell is full, and sulfur is highly…

What causes polarization in noble gases?

According to my knowledge, polarization occurs when in a compound there is a difference of polarity its constituents. But in the case of noble gases, there is a single component. What exactly is polarization of noble gases and how does it occur?

Polar vs. Amphipathic

How can I tell if a molecule is purely polar or amphipathic? For example, fatty acids are amphipathic because they have a polar carboxyl group and a non polar chain of hydrocarbons. However, sometimes there are molecules that have hydrocarbon…

without using electronegativity, which one of these molecules is polar?

If we are given 5 molecules without their electronegativity BrF5 PBr5 CCl4 XeF2 XeF4 How to determine that one of them is polar or not ? I know by using the difference in electronegativity we can determine the polarity But again, electronegativity…

How to determine whether a solvent is polar or unpolar?

I'm going to get different solvents with different bonding types (polar and non polar) and put different solutes with an "unknown" bond type to test whether or not the solute is polar or non polar The question is, can I improve this in anyway or…
