Which of the following are characteristics of ionic
Margarita [4]

Answer:

  • have high melting and boiling points
  • are hard
  • are good conductors of electricity when  dissolved in water

Explanation:

Ionic compounds are compounds that are formed between a metal and non-metal with a significant electronegativity difference. The metals transfers their electrons to the non-metals and the electrostatic attraction of the ions brings about the bonding that forms the compound.

Ionic compounds are diverse in nature and form.

Here are some of their properties:

  • They are usually hard solids with a high melting point or liquids with high boiling points
  • They are soluble in water and non-soluble in non-polar solvents
  • They are able to conduct electricity in molten form.
  • They undergo very fast reaction in aqueous solutions.

Rank the following substances in order from most soluble in water to least soluble in water: ethane, C2H6; 2-butanol, C4H9OH; po
stealth61 [152]

Answer:

Potassium chloride > Butanol >Propane > Ethane

Explanation:

Water is a polar solvent and it is likely to dissolve polar molecules.

KCl is ionic in nature and is completely polar and the solubility of the salt, potassium chloride is the highest.

Butanol can form hydrogen bonding with the water despite having a carbon chain. Thus, butanol will be at second.

Taking about, ethane and propane, both are non polar and least likely to dissolve in water. But, the extent of the London forces increases with the increase in the molecular weight. So, propane will dissolve faster than ethane.

The order is:

Potassium chloride > Butanol >Propane > Ethane
