Which formulas represent ionic compounds and which represent covalent compounds?
- a. CO2
- b. H2SO4
- c. KF
- d. CH5N
(a)
Interpretation:
The type of bond (ionic or covalent) formed in carbon dioxide
Concept Introduction:
Ionic bonds: An ionic bond is formed by combination of a metal and a nonmetal. Ionic bonds formed by the transfer of electrons from one element to other.
Example: The bonds in
Covalent bonds: A covalent bond is formed by combination of two nonmetals (or) by combination of a nonmetal with a metalloid. It is formed by sharing of electrons between two atoms.
Example: The bonds in
Answer to Problem 3.33UKC
The type of bond in carbon dioxide is covalent.
Explanation of Solution
Carbon dioxide is formed by combination of carbon (a nonmetal) and oxygen (a nonmetal). The type of bond that results in the formation of carbon dioxide is covalent bond because mutual sharing of electrons by carbon and oxygen takes place.
(b)
Interpretation:
The type of bond (ionic or covalent) formed in sulfuric acid
Concept Introduction:
Refer to part (a).
Answer to Problem 3.33UKC
The type of bond in sulfuric acid is covalent.
Explanation of Solution
Sulfuric acid is formed by the combination of sulfur (a non-metal), hydrogen (a non-metal) and oxygen (a nonmetal). The type of bond in sulfuric acid is covalent as the bonds are formed by mutual sharing of electrons between the atoms of hydrogen, sulfur and oxygen.
(c)
Interpretation:
The type of bond (ionic or covalent) formed in potassium fluoride
Concept Introduction:
Refer to part (a).
Answer to Problem 3.33UKC
The type of bond in potassium fluoride is ionic.
Explanation of Solution
Potassium fluoride is formed by the combination of potassium (an alkaline metal) and fluorine (a nonmetal). The type of bond in potassium fluoride is ionic bond because the transfer of electrons takes between a metal (potassium) and nonmetal (fluorine).
(d)
Interpretation:
The type of bond (ionic or covalent) formed in
Concept Introduction:
Refer to part (a).
Answer to Problem 3.33UKC
The type of bond in
Explanation of Solution
The type of bond formed in
