Particles bond to achieve a stable electronic configuration, such as the octet structure. A covalent bond is when 2 atoms (usually non-metals) share electrons with each other such that both atoms can get to gain the negative charge of 1 or more electrons.
Such bonds are hard to break because they are very strong. Hence, molecules with covalent bonds are hard to melt.
Covalent bonds generally have lower melting points compared to ionic or metallic bonds, as they are typically weaker. However, there are exceptions, such as diamond, which has a very high melting point due to its strong covalent bonds.
Covalent structures have high melting points because the covalent bonds between atoms are strong and require a significant amount of energy to break. This high energy barrier results in a high melting point for covalent structures.
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.
Covalent compounds have lower melting points compared to ionic compounds because covalent bonds are generally weaker than ionic bonds. In covalent compounds, individual molecules or atoms are held together by shared electrons, which are weaker than the electrostatic attraction in ionic compounds. Hence, less energy is required to break the bonds in covalent compounds, resulting in lower melting points.
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

These are solids with covalent bonds.

Compared to ionic compounds, covalent compounds have relatively low melting and boiling points because covalent bonds are not as strong as ionic bonds, and it is the bonds which hold materials together in the solid, or more solid phases.
The type of chemical bonds in a compound can influence its melting point. Compounds with stronger bonds, such as ionic or network covalent bonds, tend to have higher melting points due to the greater amount of energy required to break these bonds. Compounds with weaker bonds, such as metallic or molecular bonds, typically have lower melting points.
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.
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).
It's due to the facts that simple covalent bonds like single bonds are weaker and longer than others bonds with tighter interactions like pi bonds (double bonds) or ionic bonds. Once the heat is turned up it excites the electrons to move from their bonded positions and the bond breaks
Ionic bonds are strong electrostatic forces of attraction between oppositely charged ions, resulting in high melting and boiling points. Covalent bonds involve the sharing of electron pairs between atoms, leading to the formation of molecules with moderate to low melting and boiling points, depending on the type of covalent bond.
