Question

With reference to ionic compounds, consider the following statements:
1. Ionic compounds are insoluble in alcohol.
2. Ionic compounds in the solid state are good conductors of electricity.
Which of these statements is/are correct?

• A. Only 1
• B. Only 2
• C. Both 1 and 2
• D. Neither 1 nor 2

Answer 1

Answer: (A)

Only 1

1.The solubility is highest in polar solvents (such as water) or ionic liquids, but tends to be low in nonpolar solvents (alcohol) because the resulting ion–dipole interactions are significantly stronger than ion-induced dipole interactions, so the heat of solution is higher.
2.When these compounds are in solid state the ions are not free to move and so do not conduct electricity in the crystal lattice.
