What compounds that have low melting points and do not usually dissolve well in water?
Compounds with low melting points that do not dissolve well in water include hydrocarbons like paraffin wax and oil, nonpolar gases like helium and neon, as well as nonpolar substances like sulfur and iodine. These compounds are held together by weak intermolecular forces, which contribute to their low melting points and insolubility in water.
What else can I help you with?
What is the difference the melting point of organic and inorganic compounds?
Generally, organic compounds have lower melting points compared to inorganic compounds due to weaker intermolecular forces such as van der Waals forces in organic compounds. Inorganic compounds tend to have higher melting points because of stronger ionic or covalent bonds between their atoms.
What tests can be performed in a lab to help identify or differentiate between an ionic and covalent compound?
Ionic compounds: conduct electricity, dissolve in water, are usually in lattice structures (crystal-like), is made from a metal and a non-metal. Covalent compounds: weak conduction of electricity if any, will not dissolve in water (not completely, anyway), are usually... not crystal-like (they're softer and squisher, usually), made from a non-metal and a non-metal.
What causes the differences in melting points and boiling points between ionic and covalent compounds molecular substances?
The differences in melting and boiling points between ionic and covalent compounds are due to the strength of the intermolecular forces present. Ionic compounds have strong electrostatic forces of attraction between oppositely charged ions, resulting in higher melting and boiling points. Covalent compounds have weaker intermolecular forces such as London dispersion forces or dipole-dipole interactions, leading to lower melting and boiling points compared to ionic compounds.
How are ionic and covalent compounds different in terms of melting and boiling point and electrical conductivity and hardness and brittleness?
Ionic compounds generally have higher melting and boiling points.
Compared with ionic compounds solid molecular compounds generally?
have lower melting and boiling points, exist as discrete molecules, and do not conduct electricity in the solid state.
Compared with the melting points of ionic compounds the melting points of molecular solids tend to be .?
Ionic compounds have a higher melting point.
Where can you find a table of melting points for compounds?
Here's a chart of elemental melting points...not compounds. http://www.chemicalelements.com/show/meltingpoint.html
How does the melting point of ionic compounds compared to that of covalent compounds?
Ionic compounds generally have higher melting and boiling points.
What is the difference the melting point of organic and inorganic compounds?
Generally, organic compounds have lower melting points compared to inorganic compounds due to weaker intermolecular forces such as van der Waals forces in organic compounds. Inorganic compounds tend to have higher melting points because of stronger ionic or covalent bonds between their atoms.
What properties do most covalent compounds have in common?
Most covalent compounds have relatively low melting and boiling points, as they are held together by weak intermolecular forces. They are usually insoluble in water but soluble in nonpolar solvents. Covalent compounds tend to be nonconductors of electricity in their solid form.
Compared With the Melting Point Of Ionic Compounds The Melting Points Of Molecular Solids Tend To Be?
Ionic compounds have a higher melting point.
What is usually a property of covalently bonded compounds?
Covalent bonded compounds have generally lower melting and boiling points, are not hard, are less conductive etc.
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.
Compounds with high melting points have?
Because they have interlocking electrons as the different elements' electrons have been 'tangled'
Which type of compound would have the lowest melting point?
Compounds bonded by covalent bonds do not necessarily have low melting points. Some have whereas some don't have.Some polymers and hydrocarbons have very high melting points. But it can be said that they don't have melting points as high as ionic compounds. It is so because ionic bonds are stronger than the covalent bonds.
Why do mixtures not have sharp melting points and boiling points?
Because they are not pure compounds !
What tests can be performed in a lab to help identify or differentiate between an ionic and covalent compound?
