Do non polar covalent compounds have high or low melting points?
Wiki User

No they have high melting and boiling points.
Don't get confused with simple molecular structures such as water and carbon dioxide which have simple covalent structures. When you heat them you are overcoming the forces BETWEEN THE MOLECULES (intermolecular/van der waals forces of attraction), NOT the actual covalent bonds themselves, like the bond betwen the C and either O in carbon dioxide.

Do ionic compounds have lower boiling points than polar covalent?
Ionic compounds have higher boiling points than covalent compounds.
What are two physical properties that differ between covalent and ionic bonds?
There are more than two. In general: Covalent compounds have low melting and boiling points while ionic compounds have high melting and boiling points. Ionic compounds are good conductors of electricity when melted, while covalent compounds are not. Ionic compounds are soluble in water, while covalent compounds are soluble in non-polar liquids. These are the essentials, but other differences exist. All of these are generalizations, exceptions do occur.
Why do polar covalent molecules have higher melting points than non polar covalent compounds?
They maintain their bonding far longer than nonpolar molecules can with the addition of heat energy. Remember their slightly negative ends will bind with the slightly positive ends of the adjacent molecule.
Is it possible for a polar covalent compound to have a lower melting point than a non-polar covalent compound?
It is not possible for the polar covalent compound to have a lower melting point than the non-polar covalent compound because they have ionic bonds.
Are covalent compounds soluble in hexane?
It depends on the compound. nonpolar covalent compounds will generally be soluble whie polar covalent compounds will not be.
Do ionic compounds have lower boiling points than polar covalent?
Ionic compounds have higher boiling points than covalent compounds.

Do the molecules of alkanes have strong intermolecular forces and high melting points?
No, alkanes are non polar compounds and have low intermolecular attraction and low melting points.

Is sugar polar or ionic?
Sugars are polar covalent compounds.
What does the formula for propane tell you about a molecule of propane?
It is a saturated hydrocarbon. It is a covalent compound and has all properties which are identical to simple covalent compounds. Low boiling and melting points, soluble in organic solvents (most simple covalent compounds are soluble in organic solvent), insoluble in water and does not conduct electricity as in does not have free ions.Its tetrahedral geometry makes it non-polar.It contains four hydrogen atoms
What is the difference between organic compound and non organic compounds?
Organic chemistry is the study of the structure, properties, and reactions of compounds containing carbon. Some of the differences between organic and inorganic compounds include: Organic: nonpolar covalent bonds, low melting and boiling points, strong odors, high flammability Inorganic: Ionic or polar bonds, water soluble, high melting and boiling points, generally odorless, and generally flame-resistant.
Is ionic compounds polar or non-polar?
Ionic compounds generally are more soluble in polar solvents than in non-polar. Strictly polar compound is a term applied to compounds with a polar covalent bond
What group of substances do not usually form organized crystal lattices in solid state Ionic compounds metals polar covalent compounds or non-polar covalent compounds?
All of them can form organized crystal lattices.
Polar covalent compound?
covalent compounds are said to be polar when shared pair of electrons are unequally distributed between the two atoms .
