and are hydrogen boding, and are ion-dipole forces.

Explanation: If the bond is formed between a metal and a non metal then it is known as ionic bond and ionic compounds have positive and negative ions and so they have ion-dipole forces. Aluminium chloride and Iron(III)bromide both are ionic as they have a bond between a metal and non metal and so both of these have ion-dipole forces.

Ammonia and ethanol both are polar molecules and we know that polar molecules have dipole-dipole forces.

A hydrogen bond could form if hydrogen is bonded with more electron negative atom(N, O or F).

In ammonia, H is bonded to N and in ethanol, H is bonded to O, so both of these molecules must have hydrogen bonding. Since hydrogen bond is stronger as compared to dipole - dipole forces, we will say that both ammonia and ethanol have hydrogen bonding.

Seria el compuesto : SO₂

Explanation:

El oxigeno molecular es aquel que tiene como valencia el numero -2, en el caso del SO₂ se necesitan dos moleculas de oxigeno para que reaccione con el azufre con valencia +2 y asi equiparar los valores de valencias para que quede 0.

Es decir que el numero de valencia del azufre es +2 y el del oxigeno es -1, (por eso no es molecular)de esta manera si no multiplicamos al oxigeno por dos o no ponemos en claro que serian dos moleculas las que reaccionan el valor de la suma de las dos valencias no nos daria 0.

Entonces para poder solucionar dicho fenomeno en el espacio de abajo a la derecha se le suma un 2 al oxigeno (O₂) y asi  el -1 se multiplica con el 2 dando como resultado una valencia total de -2 (para el oxigeno) que da 0 al sumarla con la +2 del azufre.
