Which of the following is the strongest intermolecular force?

The strongest intermolecular force is hydrogen bonding, which is a particular subset of dipole-dipole interactions that occur when a hydrogen is in close proximity (bound to) a highly electronegative element (namely oxygen, nitrogen, or fluorine).

Which of the following halogens would have the highest boiling point?

Melting and Boiling Points (increases down the group)

What type of intermolecular forces increase with the molar mass?

Dispersion forces tend to increase with increasing molar mass.

Which intermolecular force is the 2nd strongest?

Intermolecular forces In the order of weakest to strongest:

• dispersion force.
• Dipole-dipole force.
• Hydrogen bond.
• Ion-dipole force.

What is the strength of dipole-dipole?

Dipole-dipole forces have strengths that range from 5 kJ to 20 kJ per mole. They are much weaker than ionic or covalent bonds and have a significant effect only when the molecules involved are close together (touching or almost touching).

Which is stronger ion dipole or dipole-dipole?

Ion–dipole and ion–induced dipole forces are stronger than dipole–dipole interactions because the charge of any ion is much greater than the charge of a dipole moment. Like a dipole–induced dipole force, the charge of the ion causes distortion of the electron cloud on the non-polar molecule.

Does astatine have a higher boiling point than bromine?

From the lowest boiling and melting point to the highest, the group in order is fluorine, chlorine, bromine, iodine and astatine. As you move down the group the halogens become darker in colour. For example fluorine is a very pale yellow whereas iodine will be dark purple in colour when it is in a vapour state.

Which has higher boiling point Cl2 or I2?

The boiling points in F2, Cl2, Br2 and I2are determined by the size of the dispersion forces between molecules. The bigger the atoms, the more polarisable their electron clouds and the greater the dispersion forces. Hence boiling points are in order: I2 > Br2 > Cl2 > F2.

What type s of intermolecular forces exist between I2 and NO3?

Ion-induced dipole forces
Ion-induced dipole forces – Intermolecular force exist between an ion and a non-polar molecule. Here the charge of the ion creates temporary dipole on non-polar molecule. e.g. I2 & NO3 −.

Why do dispersion forces increase with increasing molar mass?

Dispersion forces increase with increasing molar mass. This is because the dispersion forces rely on the contacts between molecules.
