Which substance has a stronger inter molecular force stearic acid or melting temp of water?
Stearic acid since it is nonpolar and H2O is polar.
How the melting point of alkenes can be increase by increasing molecular mass?
Increasing the molecular mass of alkenes leads to stronger London dispersion forces between molecules, which requires more energy to overcome and results in a higher melting point. The larger and heavier molecules have more electron density, leading to a larger surface area for interaction between molecules, thereby increasing the strength of intermolecular forces.
Which matter has the minimum inter molecular force?
Intermolecular forces are weak in gases.
Will the melting point rise if the force of the attraction between positive and negative ions?
Yes, if the force of attraction between positive and negative ions increases, the melting point of the ionic compound will generally rise. Stronger ionic bonds require more energy to break apart, which translates to a higher melting temperature. Conversely, if the ionic attraction weakens, the melting point would decrease.
What intermolecular force affects melting point the least?
Van der Waals forces
What force cause runoff?
melting snow
Why do molecular substances with weak inter-molecular forces have low melting points?
The cause is just this weak intermolecular force, ease to be broken.
Which substance has a stronger inter molecular force stearic acid or melting temp of water?
Stearic acid since it is nonpolar and H2O is polar.
What attractive force would cause the highest boiling point?
These are ionic bonds.
Which has a higher boiling point CO2 or SiO2?
intermolecular force between the sio2 molecule is greater than that of the co2 molecule....the co2 molecule is in it gaseous state while that of the sio2 is crystalline making the intermolecular force stronger than that of the co2 molecule.
Why do molecular solids usually have lower melting points than ionic solids?
The electrostatic force between the positive ions and the negative ions are very strong, so it requires a large amount if energy to break them. The attractive force between covalent molecular is weak, so less heat energy is required to break it.
What is molecular force?
The force between two molecules.
What is an example of autogenous welding?
An autogenous weld is one where filler metal is not used for joining. the weld is produced by fusion of the parts by melting. It does not use force to bond the parts, only the heat produced which cause melting of the base materials.
How the melting point of alkenes can be increase by increasing molecular mass?
Increasing the molecular mass of alkenes leads to stronger London dispersion forces between molecules, which requires more energy to overcome and results in a higher melting point. The larger and heavier molecules have more electron density, leading to a larger surface area for interaction between molecules, thereby increasing the strength of intermolecular forces.
What is the bond associated with CH4?
CH4 ia not polar.So the intra molecular force is london force
What does the gravitational force in a molecular cloud depends on?
The gravitational force in a molecular cloud depends on the mass of the cloud and the distance between particles. The force is stronger when there is more mass within the cloud and when particles are closer together.
What is the weakest force of molecular attraction?
Dispersion forces
