What kind of solid tends to have the lowest melting points?
Molecular compounds tend to have the lowest melting points.
What is the melting point for covalent?
Covalent bonds do not melt. Compounds with covalent bonds melt and the melting point depends primarily on whether there are discrete molecules held together by intermolecular forces (which have lower melting points) or giant covalent networks such as in silica or diamond (which tend to have higher melting points).
What compounds will have the highest melting point CO2 CaCl2 N2H4 or SCl6?
CaCl2 is ionic, is solid and will have the highest melting point. The rest are covalent compounds.
what has higher melting points ionic or covalent compounds?
Ionic compounds have higher melting points because the bond olding the ionic crystal together is stronger than the intermolecular forces (van der Waals) holding covalent molecules together. Giant covalent molecules such as dialmond and silicon dioxide have very high melting points because the lattice is held together by stong covalent bonds
Why do solid compounds have higher melting points than solid covalent compounds?
Solid molecular covalent compounds consist of molecules held together with intermolecular forces, such as dipole dipole interactions and london dispersion forces.Covalent compounds which are giant molecules such as found in diamond or silica are in fact high melting as the strong covalent bonds have to be broken to break down the crystal.Ionic compounds are generally high melting as the strong ionic bonds have to be broken to break down the crystal lattice.

Are melting points of covalent compounds high or low compared to ionic compounds?
Ionic compounds have strong electrostatic force of attraction and hence have higher melting points than covalent compounds.
Who has higher melting points ionic compounds or covalent compounds?
Ionic compounds have higher melting points than covalent compounds. Common table salt, sodium chloride, is an ionic compound and has a melting point of 801 oC. Table sugar, sucrose, a covalent compound, has a melting point of about 186 oC.
How does the melting point of ionic compounds compared to that of covalent compounds?
Ionic compounds generally have higher melting and boiling points.
Why do covalent compounds have lower melting points then ionic compounds?
Covalent compounds tend to be negatively charged than an ionic compound.
Why do covalent substaces have low melting points?
because covalent compounds form distinct molecules, in which the atoms are bound tightly to one another. Unlike in ionic compounds, these molecules don't interact with each other much (except through relatively weak forces called "intermolecular forces"), making them very easy to pull apart from each other. Since they're easy to separate, covalent compounds have low melting and boiling points.
Why organic compounds have low melting and bioling points?
Organic compounds generally are long hydrocarbon chains which are only attracted to each other by Van der Waals bonds which are the weakest intermolecular bonds. Since the bonds between molecules are weaker, they tend to melt much more quickly then stronger intermolecular bonded molecules.
How does melting point compare among molecular compounds and ionic compounds?
Molecular compounds tend to have lower melting points.
