Does covalent bonds have high melting points?
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.
Does covalent structures have high or low boiling points?
It depends on the type of structure; simple covalent structures (like water) generally have low boiling points, while giant covalent structures (like diamond) have high boiling points.
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.
Is A compound with a high melting point ionic or covalent?
A compound with a high melting point is more likely to be ionic rather than covalent. Ionic compounds have strong electrostatic forces between oppositely charged ions, resulting in high melting points. Covalent compounds typically have lower melting points because they are held together by weaker intermolecular forces.
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 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).
Why do giant covalent substances have a high melting point and boiling point?
This is because they have extremely strong covalent bonds that operate in 3D and firmly hold together all the atoms in the lattice structure. Why the bonds are so strong? Probably (and don't quote me here) because the bonds are extremely stable as a result of hybridisation. Consequently, a lot of energy is required to break or even weaken these bonds, hence the exceptionally high melting and boiling points,
What does giant covalent mean?
Giant covalent structures are substances in which atoms are bonded together by strong covalent bonds in a continuous network, forming a three-dimensional structure. Examples include diamond, graphite, and silicon dioxide (silica). These substances typically have high melting points and are insoluble in most solvents.
Compounds with high melting points have?
Because they have interlocking electrons as the different elements' electrons have been 'tangled'
Are melting points of covalent compounds high or low compared to ionic compounds?
Melting points of covalent compounds are generally lower than those of ionic compounds. This is because covalent compounds have weaker intermolecular forces compared to the strong electrostatic forces present in ionic compounds, so they require less energy to break apart the molecules.
Why do simple covalent bonds have low melting and boiling point?
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
Can you compare and contrast the 4 types of crystals?
Covalent, Metallic, and Ionic crystals have high melting points and densities, but molecular crystals tend to be soft and has a lower melting point. Covalent crystal=covalent bond and Ionic crystal=ionic bond.
