Question

11) Which statement about covalent bonds is true? A) Covalent bonds are generally weaker than ionic bonds because they form full oppositely charged particles. B) Covalent bonds are generally stronger than ionic bonds because they form full oppositely charged particles. C) Covalent bonds are generally weaker than ionic bonds because they overlap electrons to fill their outer shell. D) Covalent bonds are generally stronger than ionic bonds because they overlap electrons to fill their outer shell.

Answer 1

Answer;

C) Covalent bonds are generally weaker than ionic bonds because they overlap electrons to fill their outer shell.

Explanation;

• Covalent bond is a type of bond that results from the sharing of electrons between two non-metal atoms.
• Ionic bond on the other is a type of bond that results from the transfer of electrons between metal atoms and non metal atoms, where a metal atom looses electrons and a non-metal atom gains electrons.
• The amount of energy required to break an given bond determines how strong a particular bond is. Ionic bonds require more energy to break as compared to covalent bond and therefore they are stronger than the covalent bonds.

Answer 2

The correct statement about covalent bonding is “(C). Covalent bonds are generally weaker than ionic bonds because they overlap electrons to fill their outer shell.”

Further Explanation:

Chemical bond:

The attraction between atoms, molecules or ions which results in the formation of chemical compounds is known as a chemical bond. It is formed either due to electrostatic forces or by the sharing of electrons. There are many strong bonds such as ionic bonds, covalent bonds, and metallic bonds while some weak bonds like dipole-dipole interactions, London dispersion forces, and hydrogen bonding.

Ionic bonds:

The ionic bond formed due to electrostatic forces of attraction between oppositely charged ions. These oppositely charged ions formed when one of the species loses electrons and gets converted into cation while the other one accepts electrons and forms anion. The compounds formed by the ions of the respective species are called ionic compounds.

Covalent bonds:

The bond that is formed by the mutual sharing of electrons between the bonded atoms is called a covalent bond. It is also known as a molecular bond. Covalent compounds or molecular compounds are those compounds which are formed by the electron sharing between two or more non-metals. The ionic bonds are stronger than the covalent bonds because ionic bond involves electrostatic force of attraction while covalent bond only includes the sharing of electrons.

Therefore the correct statement is (C) that says covalent bonds are generally weaker than ionic bonds because they overlap electrons to fill their outer shell.
