Is methane a compound consisting of molecules held together by weak intermolecular forces?
Given that methane is a gas at room temperature, we can see that its molecules are attracted to each other only by weak intermolecular forces. But normally, if I say "methane is a compound consisting of..." the statement concludes, one carbon atom and four hydrogen atoms. That's what the methane molecule consists of.

Distinguish between a molecule and compound?
A molecule is the smallest unit of a chemical substance that retains its chemical properties, consisting of two or more atoms held together by chemical bonds. A compound is a substance composed of two or more different elements chemically bonded together in fixed proportions. In essence, all compounds are molecules, but not all molecules are compounds.
Will a compound with a boiling of 68C is likely to be a network structure or in the form of individual molecules?
A compound with a boiling point of 68°C is more likely to exist as individual molecules rather than a network structure. Network structures typically have higher boiling points due to the strong intermolecular forces holding the structure together. Lower boiling points are indicative of weaker intermolecular forces, suggesting that the compound is composed of individual molecules that can easily separate from each other at lower temperatures.
How do intermolecular forces effect of the properties of a substance?
A compound where the molecules are distant from each other is most likely a gas. Liquids and solids haves molecules that are closer together, with solids having the least space between molecules. As the temperature of the compound drops, molecules move closer together. There are exceptions to this rule, water for instance, has more space between its molecules when frozen.
What are molecules of two different substances called when cling together?
When molecules of two different substances cling together, they are called "adhesion". This is usually due to intermolecular forces between the molecules of the two substances, resulting in them sticking together.
How do intermolecular forces determine a substance's state?
If the intermolecular forces are great enough they can hold the molecules together as a liquid. If they are even stronger they will hold the molecules together as a solid. Water has nearly the same mass as methane and ammonia molecules, but the greater molecular forces between water molecules causes the water to be liquid at room temperature, while ammonia and methane, with weaker intermolecular forces, are gases at room temperature.
What is the force between the molecules of a compound?
The force between molecules of a compound is called intermolecular force. It is weaker than the chemical bonds holding the atoms together within a molecule. Intermolecular forces include van der Waals forces, hydrogen bonding, and dipole-dipole interactions.

Why do gases difuses but not solid?
The intermolecular forces holding gas molecules together are not very strong and thus the molecules are free to move around freely. This allows diffusion. The intermolecular forces holding molecules of a solid together are rather strong, and the molecules thus cannot move very freely. This prevents diffusion.
Is NCl3 a molecular solid?
No, NCl3 is not a molecular solid. It is a covalent compound consisting of nitrogen and chlorine atoms bonded together covalently to form molecules. In a molecular solid, the particles are individual molecules held together by weak intermolecular forces rather than a network solid held together by strong covalent bonds.
What happens to compounds at molecular level when melted?
When a compound melts, the intermolecular forces holding the molecules together weaken, allowing the molecules to move past each other and flow freely. The molecules do not break apart or undergo any chemical changes during melting.
What type of intermolecular forces hold morphine molecules together?
hydrogen bonds
When two molecules bond together the process that binds them is called?
This is an intermolecular bond.
What is the difference between an intermolecular and an intramolecular bond?
An intermolecular bond is a bond between molecules that holds them together in a substance, while an intramolecular bond is a bond within a single molecule that holds its atoms together. In general, intermolecular bonds are weaker than intramolecular bonds.
How are intermolecular forces different from forces that bind atoms together into molecules?
1. Intermolecular forces are the forces between molecules, while chemical bonds are the forces within molecules. 2. Chemical bonds combine atoms into molecules, thus forming chemical substances, while intermolecular forces bind molecules together. 3. Chemical bonding involves the sharing or transferring of electrons, while intermolecular forces do not change the electron stucture of atoms. 4. Intermolecular forces hold objects together, while chemical bonds hold molecules together.
What is the correct order of states from least to greatest intermolecular forces of attraction?
The correct order is: gas < liquid < solid. This is because in the gas phase, molecules are far apart and have weak intermolecular forces, in the liquid phase, molecules are closer together with moderate intermolecular forces, and in the solid phase, molecules are tightly packed with strong intermolecular forces.
The forces of attraction between molecules in a molecular compound are generally?
The forces of attraction between molecules in a molecular compound are generally weaker than those in an ionic compound. These forces are typically known as van der Waals forces or London dispersion forces, which are based on temporary fluctuations in electron distribution within the molecules. The strength of these forces can vary depending on the molecular structure and shape of the compound.
Will a compound with a boiling of 68C is likely to be a network structure or in the form of individual molecules?
A compound with a boiling point of 68°C is more likely to exist as individual molecules rather than a network structure. Network structures typically have higher boiling points due to the strong intermolecular forces holding the structure together. Lower boiling points are indicative of weaker intermolecular forces, suggesting that the compound is composed of individual molecules that can easily separate from each other at lower temperatures.
