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
