Place the following types of attraction weakest to strongest: dispersion ionic bond single covalent bond hydrogen bond dipole interaction

The order from weakest to strongest is:

Explanation:

Dispersion force is the weakest intermolecular force. It is a temporary attractive force that come into action when the electrons in two neighboring atoms are at the positions which results in formation of temporary dipoles.

Dipole interaction is an attractive interaction between the positive end and negative end of the polar molecule.

Hydrogen bond is a weak bond between two adjacent molecules due to an electrostatic attraction between a hydrogen atom in a molecule with an electronegative atom of an adjacent molecule.

Single covalent bond is more stronger bond than the the interaction stated above because there is sharing of an electron between two atoms.

Ionic bond is the strongest bonds in which complete transfer of electrons is present. Due to high electronegativity difference between the bonded atoms there is a high electrostatic interaction between the oppositely charged ions which makes ionic bond strongest from all the other types of the bonds.

So, the order is:

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
