Which of the following explains why the entropy change is greater for the dissolution of nai compared to the dissolution of nabr?
a. iodide has weaker ion-dipole interactions with water than bromide.
b. the interactions between bromide ions with other bromide ions is stronger than the interactions between iodide ions with other iodide ions.
c. the more negative change in enthalpy observed with nai implies greater dissociation and hence greater entropy.
d. the bromide ion has more negative charge than the iodide ion. therefore, because of the greater charge, it forms a stronger ion-dipole network with water.
e. the cation forms stronger ion-dipole networks with water in nabr than nai because of the weaker bond to br.
