How do properties of ionic and molecular compounds differ?
Solution
Hint Molecular compounds also known by the name of covalent compounds. Ionic compounds and molecular compounds differ in many properties because there is a difference in the internal bonding of atoms present in the molecule.
Complete step by step solution:
Some important points regarding ionic compounds are as follow:
-As the name suggested that ionic compounds are formed through the ionic bonding between two oppositely charged ions.
-Ionic bonds are formed due to high force of attraction.
-Boiling point of ionic compounds is high.
-Melting point of ionic compounds is high due to strong attraction.
-Ionic compounds in the molten state are good conductors of electricity due to the presence of charged ions in it.
-Ionic compounds are easily soluble in water as after breakdown it will be converted into cations and anions.
-Ionic compounds are generally present in the solid state and it is hard and brittle in nature.
Some important points regarding molecular / covalent compounds are as follow:
-As the name suggested that covalent compounds are formed through the covalent bonding between two atoms.
-Covalent bonds are formed due to sharing of electrons.
-Boiling point of covalent compounds is lower than ionic compounds.
-Melting point of covalent compounds is also low due to very less attraction between atoms.
-Covalent compounds are bad conductors of electricity as they are not having free ions or electrons.
-Covalent compounds are not easily soluble in water as after breakdown it is not sure that it will convert into cations and anions.
-Covalent compounds when present in the solid state are hard in nature.
Note: Here some of you think that why ionic bond is stronger than covalent bond, so the reason is that in ionic bond a greater attraction force is present which is not present in the covalent bonds.
