Introduction

Chemistry is a vast and fascinating field that deals with the study of the composition, properties, and reactions of matter. In this field, there are various types of chemical bonds that hold atoms together in molecules. One such type of bond is the coordinate covalent bond, which plays a crucial role in the formation of certain molecules. In this article, we will explore the concept of coordinate covalent bonds and identify which of the given options is made up of this type of bond.

What is a Coordinate Covalent Bond?

A coordinate covalent bond, also known as a dative covalent bond, is a type of chemical bond that involves the sharing of a pair of electrons between two atoms. In this type of bond, one atom provides both electrons in the shared pair, while the other atom provides none. This type of bond is typically found in molecules where one atom has a lone pair of electrons that it can donate to another atom.

Characteristics of Coordinate Covalent Bonds

Coordinate covalent bonds have several characteristics that distinguish them from other types of chemical bonds. Some of the key characteristics of coordinate covalent bonds include:

Electron donation: In a coordinate covalent bond, one atom donates a pair of electrons to another atom.
No electron sharing: Unlike covalent bonds, where both atoms share a pair of electrons, in a coordinate covalent bond, one atom provides both electrons in the shared pair.
Polar nature: Coordinate covalent bonds are typically polar in nature, meaning that the bond is not symmetrical and has a partial positive charge on one atom and a partial negative charge on the other.

Examples of Coordinate Covalent Bonds

Coordinate covalent bonds are found in a variety of molecules, including:

Ammonia (NH3): In ammonia, the nitrogen atom donates a pair of electrons to the hydrogen atoms, forming a coordinate covalent bond.
Carbon monoxide (CO): In carbon monoxide, the carbon atom donates a pair of electrons to the oxygen atom, forming a coordinate covalent bond.
Aluminium bromide (AlBr3): In aluminium bromide, the aluminium atom donates a pair of electrons to the bromine atoms, forming a coordinate covalent bond.

Which of the Given Options is Made Up of a Coordinate Covalent Bond?

Now that we have discussed the concept of coordinate covalent bonds and their characteristics, let's examine the given options to determine which one is made up of this type of bond.

A. Sodium chloride (NaCl): Sodium chloride is an ionic compound that consists of sodium and chloride ions held together by ionic bonds. It does not contain a coordinate covalent bond.
B. Ammonia (NH3): Ammonia is a molecule that contains a coordinate covalent bond between the nitrogen and hydrogen atoms.
C. Chlorine (Cl2): Chlorine is a diatomic molecule that consists of two chlorine atoms held together by a covalent bond. It does not contain a coordinate covalent bond.
D. Aluminium bromide (AlBr3): Aluminium bromide is a molecule that contains a coordinate covalent bond between the aluminium and bromine atoms.
E. Carbon monoxide (CO): Carbon monoxide is a molecule that contains a coordinate covalent bond between the carbon and oxygen atoms.

Introduction

In our previous article, we explored the concept of coordinate covalent bonds and identified which of the given options is made up of this type of bond. In this article, we will delve deeper into the world of coordinate covalent bonds and answer some frequently asked questions about this fascinating topic.

Q: What is the difference between a coordinate covalent bond and a covalent bond?

A: A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons. In a coordinate covalent bond, one atom donates a pair of electrons to another atom, whereas in a covalent bond, both atoms share a pair of electrons.

Q: What are some examples of molecules that contain coordinate covalent bonds?

A: Some examples of molecules that contain coordinate covalent bonds include ammonia (NH3), carbon monoxide (CO), and aluminium bromide (AlBr3).

Q: What are the characteristics of a coordinate covalent bond?

A: The characteristics of a coordinate covalent bond include:

Electron donation: One atom donates a pair of electrons to another atom.
No electron sharing: Unlike covalent bonds, where both atoms share a pair of electrons, in a coordinate covalent bond, one atom provides both electrons in the shared pair.
Polar nature: Coordinate covalent bonds are typically polar in nature, meaning that the bond is not symmetrical and has a partial positive charge on one atom and a partial negative charge on the other.

Q: What is the significance of coordinate covalent bonds in chemistry?

A: Coordinate covalent bonds play a crucial role in the formation of certain molecules and are found in a variety of biological and chemical systems. They are also important in the study of chemical reactivity and the design of new materials.

Q: Can coordinate covalent bonds be found in ionic compounds?

A: No, coordinate covalent bonds are typically found in covalent compounds, not ionic compounds. Ionic compounds are formed when one or more electrons are transferred from one atom to another, resulting in the formation of ions with opposite charges.

Q: How do coordinate covalent bonds differ from hydrogen bonds?

A: Coordinate covalent bonds differ from hydrogen bonds in that they involve the sharing of a pair of electrons between two atoms, whereas hydrogen bonds involve the attraction between a hydrogen atom and a highly electronegative atom, such as oxygen or nitrogen.

Q: Can coordinate covalent bonds be broken?

A: Yes, coordinate covalent bonds can be broken, just like any other type of chemical bond. This can occur through various mechanisms, including the addition of a catalyst or the application of heat or light.

Q: What are some common applications of coordinate covalent bonds?

A: Coordinate covalent bonds have a wide range of applications in chemistry and biology, including:

Catalysis: Coordinate covalent bonds are involved in many catalytic reactions, where a molecule is converted into a product through the action of a catalyst.
Materials science: Coordinate covalent bonds are used to design new materials with unique properties, such as high strength or conductivity.
Biological systems: Coordinate covalent bonds play a crucial role in many biological systems, including the formation of proteins and the regulation of gene expression.
