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.
Non-polar covalent compounds typically have low melting points, as they consist of molecules held together by weak van der Waals forces. These forces are relatively weak compared to ionic or metallic bonds, resulting in low melting points for non-polar covalent compounds.
Every covalent bond has its individual melting point but covalent bonds always have lower melting points than ionic bonds
Compared to ionic compounds, Molecular compounds generally have lower melting points and boiling points.
Non polar compounds usually have lower melting point, meanwhile some compounds including diamond, graphite are exceptional with melting points over 3000 K.

Why do polar covalent molecules have higher melting points than non polar covalent compounds?
Polar covalent molecules have higher melting points than nonpolar covalent compounds because the presence of polar bonds leads to stronger intermolecular forces, such as dipole-dipole interactions and hydrogen bonding. These stronger forces require more energy to overcome, resulting in a higher melting point for polar covalent molecules.
Do ionic compounds have lower boiling points than polar covalent?
In general, ionic compounds tend to have higher boiling points compared to polar covalent compounds. This is because ionic compounds have strong electrostatic forces of attraction between positively and negatively charged ions, requiring more energy to break those bonds compared to the intermolecular forces found in polar covalent compounds.
Do non polar molecules have high melting points?
No, nonpolar molecules generally have low melting points. This is because nonpolar molecules tend to have weak intermolecular forces, such as London dispersion forces, which are easily overcome. High melting points are typically associated with compounds with strong intermolecular forces, such as ionic or covalent network compounds.
What are two physical properties that differ between covalent and ionic bonds?
In covalent bonds, atoms share electrons, resulting in localized electron density between the two atoms, leading to weaker bonds. In contrast, ionic bonds involve the transfer of electrons from one atom to another, resulting in the formation of ions with opposite charges, leading to stronger electrostatic interactions.
Do Covalent compounds boil at higher temperatures than ionic bonds or lower temperatures than ionic bonds?
Covalent compounds generally have lower boiling points than ionic compounds. This is because covalent compounds are held together by weaker intermolecular forces compared to the strong electrostatic forces in ionic compounds.

What are two major characteristics of molecular compounds?
Molecular compounds are formed by sharing electrons between atoms through covalent bonds. Molecular compounds typically have low melting and boiling points compared to ionic compounds.

Is it possible for a polar covalent compound to have a lower melting point than a non-polar covalent compound?
Yes, it is possible. Melting point is influenced by various factors beyond just the polarity of the compound, such as molecular size, shape, and intermolecular forces. A polar covalent compound with weaker intermolecular forces can have a lower melting point than a non-polar covalent compound with stronger intermolecular forces.
What are the effects of covalent and ionic substances?
Covalent substances tend to have lower melting and boiling points, are often softer, and may not conduct electricity well. Ionic substances typically have higher melting and boiling points, are typically hard and brittle, and can conduct electricity when dissolved in water or molten.
What is the properties of covalent bond?
Covalent compounds generally have much lower melting and boiling points that ionic compounds. Covalent compounds are soft and squishy. Covalent compounds tend to be more flammable that ionic compounds. Covalent compounds don't conduct electricity in water. Covalent compounds aren't usually very soluble in water.
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.
Are covalent soluble?
Covalent compounds can be soluble, depending on their polarity and structure. Covalent compounds that form hydrogen bonds or have polar groups are more likely to be soluble in polar solvents, while nonpolar covalent compounds are more likely to be soluble in nonpolar solvents.
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.
