Intermolecular forces are the forces of attraction that exist between molecules in a compound. The stronger the attractions between particles the more difficult it will be to separate them. When substances boil, the particles are completely separated from one another and the attractions between the molecules are completely overcome.
What else can I help you with?
Why do covalent compounds and ionic compounds have different melting points?
Melting points are a reflection of the intermolecular forces and intramolecular forces of the compound. The stronger the intermolecular force, the more energy it takes to bring it to a different state.
Do ionic compounds or convalent compounds have a high volatility?
Ionic compounds generally have a higher volatility compared to covalent compounds. This is because ionic compounds have weaker intermolecular forces that allow them to break apart and vaporize more easily at lower temperatures. Covalent compounds tend to have stronger intermolecular forces, making them less likely to evaporate at the same rate.
Which is stronger intramolecular or intermolecular force in the case of covalent bond?
In the case of a covalent bond, the intramolecular force is stronger than the intermolecular force. The covalent bond holds atoms together within a molecule, while intermolecular forces are weaker interactions between molecules.
What can you say about the relative strength of the intermolecular forces in the two compounds?
The relative strength of intermolecular forces depends on the types of molecules involved. Compounds with hydrogen bonding, such as water, tend to have stronger intermolecular forces compared to those with only London dispersion forces, like diethyl ether. This results in higher boiling points for compounds with stronger intermolecular forces.
Why do most solid covalent compounds have lower melting points than ionic compounds?
Solid covalent compounds have weaker intermolecular forces compared to the strong electrostatic forces present in ionic compounds. This results in lower melting points for covalent compounds since less energy is required to break the intermolecular forces holding the molecules together.
Why is ionc compounds stronger than covalent compounds?
Ionic compounds have a stronger bond due to the electrostatic attraction between oppositely charged ions, resulting in a lattice structure. Covalent compounds share electrons between atoms, which may not be as strong as the attraction between ions in ionic compounds.

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.
Why do melting points of covalent compounds tend to be lower than those of ionic compounds?
Covalent compounds typically have weaker intermolecular forces compared to the strong electrostatic forces present in ionic compounds. This results in covalent compounds having lower melting points as less energy is required to break the intermolecular forces and transition from solid to liquid. Additionally, covalent compounds generally have a more disordered structure, which further contributes to their lower melting points.
Do covalent compounds have lower boiling point than ionic compounds?
In general, covalent compounds have lower boiling points than ionic compounds. This is because covalent compounds have weaker intermolecular forces compared to the strong electrostatic forces between ions in ionic compounds. As a result, less energy is required to overcome the intermolecular forces in covalent compounds, leading to lower boiling points.
Are the intramolecular forces in paradichlorobenzene stronger than the intermolecular forces?
Yes, intramolecular forces such as covalent bonds in paradichlorobenzene are stronger than intermolecular forces like van der Waals forces between molecules. Intramolecular forces hold atoms within a molecule together, while intermolecular forces act between molecules.
What is stronger intermolecular or intra?
Intra-molecular forces are stronger than intermolecular forces because intra-molecular forces act within a molecule to hold its atoms together, such as covalent bonds. Intermolecular forces act between molecules and are generally weaker, like van der Waals forces or hydrogen bonding.
Are covalent compounds soluble in hexane?
Yes, covalent compounds are generally soluble in nonpolar solvents like hexane due to their similar polarity. Covalent compounds tend to dissolve well in nonpolar solvents because they share similar intermolecular forces, such as London dispersion forces.
