Answer : The covalent compounds are, SiF₄, CO₂, S₇O₂, PCl₃, H₂O and S₂F₁₀

Explanation :

Covalent compound : It is defined as the compound which is formed by the sharing of electrons between the atoms forming a compound.

The covalent compound are usually formed when two non-metals react.

Ionic compound : It is defined as the compound which is formed when electron gets transferred from one atom to another atom.

Ionic compound are usually formed when a metal reacts with a non-metal.

KBr

It is an ionic compound because potassium element is a metal and bromine element is a non-metal. The bond formed between a metal and a non-metal is always ionic in nature.

SiF₄

It is a covalent compound because sharing of electrons takes place between silicon and fluorine. Both the elements are non-metals and hence, will form covalent bond.

Al₂O₃

It is an ionic compound because aluminum element is a metal and oxygen element is a non-metal. The bond formed between a metal and a non-metal is always ionic in nature.

CO₂

It is a covalent compound because sharing of electrons takes place between carbon and oxygen. Both the elements are non-metals and hence, will form covalent bond.

NaCO₃

It is an ionic compound because sodium element is a metal and carbon element is a non-metal. The bond formed between a metal and a non-metal is always ionic in nature.

S₇O₂

It is a covalent compound because sharing of electrons takes place between sulfur and oxygen. Both the elements are non-metals and hence, will form covalent bond.

PCl₃

It is a covalent compound because sharing of electrons takes place between phosphorus and chlorine. Both the elements are non-metals and hence, will form covalent bond.

Fe₃N₂

It is an ionic compound because iron element is a metal and nitrogen element is a non-metal. The bond formed between a metal and a non-metal is always ionic in nature.

H₂O

It is a covalent compound because sharing of electrons takes place between hydrogen and oxygen. Both the elements are non-metals and hence, will form covalent bond.

S₂F₁₀

It is a covalent compound because sharing of electrons takes place between sulfur and fluorine. Both the elements are non-metals and hence, will form covalent bond.

Hence, the covalent compounds are, SiF₄, CO₂, S₇O₂, PCl₃, H₂O and S₂F₁₀
