Answer:
True
Explanation:
All the above statements buttress the fact that the larger molecule, the greater the magnitude of London forces between the molecules. Each of the statements above is a confirmation/explanation of this general rule.
Answer:
It does not contain free mobile ions
Explanation:
Solid sodium chloride does not conduct electricity because it does not contain free mobile ions.
- Although sodium chloride is an ionic compound, in solid state, there is absence of free mobile ions.
- In aqueous solutions or in molten form, ionic compounds can conduct an electric current using free mobile ions as carriers.
- Therefore, they are electrolytes.
In solid state ions are arranged into crystal lattice and will not conduct a current of electricity.
