Which substance most likely has the highest boiling point?
2 answers:
Answer: The correct answer is calcium chloride , an ionic compound.
Explanation:
Ionic compounds are the compounds in which complete transfer of electrons takes place from one element to another. In these compounds, the forces of attraction between the particles is strong and hence, they have the highest boiling points.
Covalent compounds are the compounds in which sharing of electrons takes place between two elements forming a bond. There are two types of covalent compounds: Polar and Non-polar.
The forces of attraction between the particles is stronger in polar covalent compounds as compared to the no-polar covalent compounds. But, the forces of attraction between covalent compounds is less than the ionic compounds.
Hence, the order of increasing boiling points is given by:
Non-polar covalent < Polar covalent < Ionic
Therefore, the correct answer is calcium chloride , an ionic compound.
