Because they have interlocking electrons as the different elements' electrons have been 'tangled'
Electrovalent compounds have high melting and boiling points because they have strong electrostatic forces of attraction between the positively charged metal ions and negatively charged non-metal ions. These forces require a significant amount of energy to overcome, resulting in high melting and boiling points for these compounds.
The structure of a compound will dictate what intermolecular forces hold the molecules together. The stronger these forces, the higher will be the boiling point.
Because they are not pure compounds !
Ionic bonds are typically responsible for creating compounds with high melting points. In ionic bonding, atoms transfer electrons to achieve a full outer shell, resulting in a strong attraction between positively and negatively charged ions. This strong electrostatic force requires more energy to break the bond and hence, compounds with ionic bonds tend to have high melting points.
Ionic bonds have high melting points and can be soluble in water. Ionic compounds have strong bonds between positive and negative ions, leading to high melting points, and they can dissolve in water due to the attraction between the ions and the water molecules.
In general, ionic compounds have high melting points due to the strong electrostatic forces holding the ions together in a lattice structure. This results in a significant amount of energy required to break these bonds, leading to high melting points.
1)brittleness 2)high melting points 3)high boiling 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.

Ionic compounds have a higher melting point.

well I dk geti don't know
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.
Ionic bonds require relatively high energies to be broken compared to the weaker hydrogen bond and van der Waals forces. Ionic compounds will thus have higher melting points than polar and organic compounds of similar molecular weight.
Here's a chart of elemental melting points...not compounds. http://www.chemicalelements.com/show/meltingpoint.html
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.
Ionic compounds are basically the combination of a metal and a non-metal. However, its high melting points and boiling points are part of the physical properties of ionic compounds, and high heat is usually required to break the bonds of ionic compounds. The ions which are held together by strong electrostatic force of attraction may results in high melting point and boiling point.
