No, ionic compounds have high melting and boiling points. This is due to the strength of the electrostatic attraction between the positively-charged and the negatively-charged ions.

How compared with the melting points of ionic compounds the melting points of molecular solids tend to be?
Ionic compounds have a higher melting point.
Why do covalent bonds generally have lower melting temperatures but are stronger than ionic bonds?
because they are lower in temperature
Why do covalent compounds have lower mealting points than ionic compouds?
Molecular covalent compounds have lower melting points because the inetrmolecular forces are weaker than ionic bonds. Note that giant covalent structures, such as silicon dioxide, can have very high melting points, the key factor is not simply the nature of the bond.
What usually has a lower melting points than the ionic solids?
Covalent compounds have a lower melting point.
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.
What has lower melting points than ionic solids?
Molecular solids
What have lower melting points than ionic solids?
These are organic compounds.
Compared with ionic compounds solid molecular compounds generally?
a lower melting point
Do non polar covalent compounds have high or low melting points?
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.
Which type of compound has the lower melting points - ionic or molecular Why?
The melting and boiling points of molecular compounds are generally quite low compared to those of ionic compounds. This is because the energy required to disrupt the inter molecular forces between molecules is far less than the energy required to break the ionic bonds in a crystalline ionic compound.
Which solid is more likely to have the lowest melting point an ionic solid or molecular solid?
Molecular Solids have a lower melting point
What usually has lower melting points than ionic solids?
Molecular solids
