Do Covalent compounds boil at higher temperatures than ionic bonds or lower temperatures than ionic bonds?
'Covalently bonded' = 'Non polar' compounds have much LOWER boiling points than polar compounds and 'ion bonded' = 'Crystallic' compounds.
(Compare: (all at STP)
- H2S (gas, linear, covalent H-S bonds) and
- H2O (liquid, non-linear, polar H-O bonds) and
- Na2O (solid, ionic, crystal, tetrahedrical(Na+) +cubic(O2-)

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 reaction of covalent compound is slow?
The reaction of covalent compounds can be slow because covalent bonds are strong and stable, requiring more energy to break compared to ionic bonds. Additionally, covalent compounds often need specific conditions such as high temperatures or the presence of a catalyst to facilitate the reaction. The lack of charged particles in covalent compounds can also slow down reaction rates compared to ionic compounds which readily form charged species.
What types of compounds are formed by covalent bonds?
Covalent bonds form between nonmetal atoms, resulting in the formation of covalent compounds. These compounds consist of molecules held together by the sharing of electron pairs between the atoms. Examples include water (H2O), carbon dioxide (CO2), and methane (CH4).
What are some differences between ionic and covalent compounds?
Covalent bonds are formed when electrons are shared, and ionic bonds are formed by electrostatic forces between bonds. Ionic bonds are generally weaker than covalent bonds, since most ions dissociate in water, but covalent compounds do not break into their elements unless with large amounts of energy added.
Why do covalent compounds have lower melting points then ionic compounds?
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.
What types of bonds are in compounds?
covalent

What covalent bonds used to form?
It is used to form molecules and various compounds. In fact, most of the bonds are covalent bonds.

Do polyatomic compounds contain only covalent bonds?
No, polyatomic compounds can contain both covalent and ionic bonds. Covalent bonds involve the sharing of electrons between atoms, while ionic bonds involve the transfer of electrons from one atom to another. Polyatomic compounds can have bonds of both types within their structure.
Is Vaseline ionic or covalent?
Petrol is a mixture of organic compounds. These organic compounds have 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.
