Answer:

NH3 ------dipole - dipole forces

CH3OH ------ dipole - dipole forces

AlBr3 ------- ion - dipole forces

AlCl3 ------- ion - dipole forces

Explanation:

Let us recall that water is a polar molecule. This means that water has a positive as well as a negative end. NH3 also has a dipole. The interaction between solute and solvent dipoles leads to the dissolution of NH3 in water. Hence the strongest intermolecular force here is dipole - dipole forces.

Similarly, CH3OH  possesses a polar -O-H group which can interact with water via dipole - dipole interaction as its strongest intermolecular force.

As for AlBr3 and AlCl3, the two substances dissociate into ions in solution and these ions interact with the dipole in water via ion - dipole interaction as its strongest intermolecular interaction.

Answer:

  • Dipole -dipole forces :

Ammonia [tex]NH_3[/tex]

Aluminium Chloride [tex]AlCl[/tex]

Methanol [tex]CH_3OH[/tex]

  • Ion dipole forces :

Aluminium bromide [tex]AlBr_3[/tex]

Explanation:

Because water is not in ionic form it can only forms dipole forces which are strongest. Methanol, Ammonia and AlCl are also dipoles not ions . Thus dipole dipole forces exist.

On the other hand, aluminium bromide are ionic and it can forms ion dipole bonds with water.
