Question

Which compound has both ionic and covalent bonding?

Answer 1

The compound that has both ionic and covalent bonding is $\boxed{\left( 1 \right){\text{ CaC}}{{\text{O}}_3}}$.

Further Explanation:

The attraction between different atoms, molecules and ions is known as a chemical bond. The formation of various types of compounds takes place as a result of these chemical bonds.

An ionic bond is formed as a result of the interaction between a metal and a non-metal. Metals have the tendency to lose electrons while non-metals tend to gain electrons. Due to this, metal atoms form cations by loss of electrons and non-metals become anions with the gain of electrons.

A covalent bond is formed by the mutual sharing of electrons between the bonded atoms. It is also called the molecular bond. Such bonds usually exist between two or more non-metals.

(1) ${\text{CaC}}{{\text{O}}_{\text{3}}}$  

Its constituents are ${\text{C}}{{\text{a}}^{2 + }}$ and ${\text{CO}}_3^{2 - }$ ions. The bond between calcium and carbonate ions is an ionic bond. But the bond between the carbon atom and the oxygen atom of carbonate is formed by sharing of electrons so it is a covalent bond. So ${\text{CaC}}{{\text{O}}_{\text{3}}}$ has both ionic and covalent bonding and therefore this option is correct.

(2) ${\text{C}}{{\text{H}}_2}{\text{C}}{{\text{l}}_2}$  

It has carbon, hydrogen and chlorine atoms. All of them are nonmetals and the bonds formed between nonmetals are covalent bonds. So ${\text{C}}{{\text{H}}_2}{\text{C}}{{\text{l}}_2}$ has only covalent bonds and therefore this option is incorrect.

(3) ${\text{C}}{{\text{H}}_3}{\text{OH}}$  

It has carbon, hydrogen and oxygen atoms. All of them are nonmetals and the bonds formed between nonmetals are covalent bonds. So ${\text{C}}{{\text{H}}_3}{\text{OH}}$ has only covalent bonds and therefore this option is incorrect.

(4) ${{\text{C}}_{\text{6}}}{{\text{H}}_{{\text{12}}}}{{\text{O}}_{\text{6}}}$  

It has carbon, hydrogen and oxygen atoms. All of them are nonmetals and the bonds formed between nonmetals are covalent bonds. So ${{\text{C}}_{\text{6}}}{{\text{H}}_{{\text{12}}}}{{\text{O}}_{\text{6}}}$ has only covalent bonds and therefore this option is incorrect.

Keywords: chemical bond, ionic bond, covalent bond, CaCO3, CH2Cl2, C2H12O6, CH3OH, carbon, hydrogen, oxygen.

Answer 2

(1) CaCO3 is the correct answer.

The type of bond formed between Ca2+ and CO3 2- is ionic, and the type of bond formed between C and O is covalent.

Hope this helps~
