Nonpolar molecules - only have dispersion forces, have relatively low boiling points compared to polar, ionic, etc, do not conduct electricity
Polar molecules - also have dispersion forces, have dipole forces (between pos. and neg. ions), can have Hydrogen bonds (if there's an H connected to either an N, O, or F)
Ionic compounds - much higher b.p.'s than molecules, most transition metals form ionic compounds (SnCl2)
What else can I help you with?
Is Caf2 polar non polar or ionic?
CaF2 is considered an ionic compound because it is composed of a metal cation (Ca) and a nonmetal anion (F) bonded together through ionic bonds. It is not considered as polar or nonpolar since ionic compounds do not have distinct polar or nonpolar characteristics as covalent compounds do.
Is ionic compounds polar or non-polar?
Ionic compounds are non-polar because they consist of ions (charged particles) held together by electrostatic forces. These compounds do not have a separation of charge within the molecule, which is characteristic of polar compounds.
Do polar compounds travel farther in TLC compared to non-polar compounds?
Yes, polar compounds typically travel farther in Thin Layer Chromatography (TLC) compared to non-polar compounds due to their stronger interactions with the polar stationary phase.
Why don't polar compounds mix with nonpolar compounds?
Polar compounds have poles that have a partial positive charge and a partial negative charge that attract other polar molecules. Nonpolar compounds do not have partially charged poles, so the polar substance is not attracted to them and they don't dissolve.
Can ethers dissolve both polar and non-polar compounds?
Yes, ethers are versatile solvents that can dissolve both polar and non-polar compounds. This dual solubility arises from the ether molecule's oxygen atom, which can form hydrogen bonds with polar compounds while the hydrocarbon chain can interact with non-polar compounds through dispersion forces.

How water disssolves ion compounds and polar compounds?
Like dissolves like. Water is polar solvent and hence it dissolves ionic and polar compounds.
Do polar compounds travel farther in TLC compared to non-polar compounds?
Yes, polar compounds typically travel farther in Thin Layer Chromatography (TLC) compared to non-polar compounds due to their stronger interactions with the polar stationary phase.
Is an ionic compound considered to be a polar or non polar compound?
ionic compounds are polar compounds because they have charge separation between them
Why don't polar compounds mix with nonpolar compounds?
Polar compounds have poles that have a partial positive charge and a partial negative charge that attract other polar molecules. Nonpolar compounds do not have partially charged poles, so the polar substance is not attracted to them and they don't dissolve.
Which compounds elute first in non polar gc column?
In a non-polar GC column, compounds with lower polarity elute first. Non-polar compounds are less attracted to the non-polar stationary phase of the column, so they move through the column faster than polar compounds.
How are polar and non-polar compounds different?
H2 non-polar (equal sharing) H20 polar (uneven sharing)
Can ethers dissolve both polar and non-polar compounds?
Yes, ethers are versatile solvents that can dissolve both polar and non-polar compounds. This dual solubility arises from the ether molecule's oxygen atom, which can form hydrogen bonds with polar compounds while the hydrocarbon chain can interact with non-polar compounds through dispersion forces.
What are two major characteristics of molecular compounds?
Low melting and boiling points. Some are polar and some are nonpolar. Those that are polar will dissolve in water. They also do not conduct electricity.
Why are salts soluble in water and not oils?
Because salts and water are polar compounds; oil components are not polar compounds.
Do polar compounds have stronger or weaker attractions between molecules?
Polar compounds have stronger attractions between molecules.
