Several of them certainly do. Furthermore, a great many
of them don't. All compounds are made of molecules.
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.
No, It is infact polar molecules that have higher melting points than non-polar molecules. Polar molecules have stronger intermolecular bonds called dipole-dipole forces. These forces are an attraction between the slightly positive end of one molecule with the slightly nehative end of another.
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).
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.
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.
No, molecules of alkanes have weak intermolecular forces (London dispersion forces) due to their simple linear structure with only van der Waals interactions. This results in low melting points for alkanes compared to many other types of compounds.
Ionic compounds generally have high melting points due to strong electrostatic forces between ions. In contrast, covalent compounds tend to have lower melting points as they consist of discrete molecules held together by weaker intermolecular forces. Additionally, metallic compounds generally have variable melting points depending on the specific metal and its bonding characteristics.
Because they have interlocking electrons as the different elements' electrons have been 'tangled'
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.
Several factors affect boiling point, including the forces between the molecules in a compound. The harder the molecules are holding on to each other, the more energy it takes to boil. Water molecules hold on to each other with hydrogen bonds, so it has relatively high boiling point.So, to answer your question, high boiling points might indicate strong intermolecular forces.
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.
