Question

In general, which attractions are stronger: intermolecular or intramolecular? Research and explain a quantitative comparison between the strength of a chemical bond and the strength of intermolecular forces of attraction.

- I understand that intramolecular forces are stronger but I don’t know what to put for the quantitative data

Answer 1

In general, intramolecular forces are stronger than intermolecular forces. The strength of a chemical bond is determined by the type of bond and the atoms involved.

Step-by-step explanation:

Intermolecular forces, which are the attractions between molecules, are generally weaker than intramolecular forces, which are the bonds within a molecule. The strength of a chemical bond is determined by the type of bond, such as covalent or ionic, and the atoms involved. Covalent bonds, which involve the sharing of electrons, are generally stronger than intermolecular forces. For example, the bond between hydrogen and chlorine in HCl requires about 430 kilojoules to break, while the intermolecular forces in liquid HCl require only about 17 kilojoules to convert it into a gas.

Answer 2

Answer is: intramolecular attractions are stronger.

Intramolecular attractions are the forces between atoms in molecule.

There are several types of intramolecular forces: covalent bonds, ionic bonds.

Intermolecular forces are the forces between molecules. The stronger are intermolecular forces, the higher is boiling point of compound, because more energy is needed to break interaction between molecules.

There are several types of intermolecular forces: hydrogen bonding, ion-induced dipole forces, ion-dipole forces andvan der Waals forces.

Hydrogen bonds are approximately 5% of the bond strength of covalent C-C or C-H bonds.

Hydrogen bonds strength in water is approximately 20 kJ/mol, strenght of carbon-carbon bond is approximately 350 kJ/mol and strengh of carbon-hydrogen bond is approximately 340 kJ/mol.

20 kJ/350 kJ = 0.057 = 5.7 %.
