Carbon And Its Compounds Class 10 Notes:
Why is carbon so important?
Carbon is important for life because it can form four bonds with other atoms. This allows carbon atoms to form long chains and complex structures. Carbon atoms can also bond with other elements, such as hydrogen, oxygen, nitrogen, and sulfur, to form a wide variety of molecules.
What are carbon compounds?
Carbon compounds are chemical substances that contain carbon. Carbon compounds are divided into two main categories: organic and inorganic. Organic compounds are the compounds that are found in living things. Inorganic compounds are the compounds that are found in non-living things.
What are the different types of carbon compounds?
There are many different types of carbon compounds, but some of the most common include:
- Hydrocarbons: These compounds are made up of carbon and hydrogen only. Hydrocarbons are found in many fuels, such as oil and natural gas.
- Alcohols: These compounds contain a hydroxyl group (-OH). Alcohols are used in a variety of products, such as solvents, disinfectants, and beverages.
- Aldehydes: These compounds contain a carbonyl group (-CHO). Aldehydes are used in many different products, such as perfumes, plastics, and food additives.
- Ketones: These compounds also contain a carbonyl group, but they are different from aldehydes in that they are attached to two carbon atoms. Ketones are used in a variety of products, such as solvents, pharmaceuticals, and food additives.
- Carboxylic acids: These compounds contain a carboxyl group (-COOH). Carboxylic acids are used in a variety of products, such as food additives, preservatives, and medicines.

1. Properties of carbon:
Tetravalency of carbon:
Carbon has four valence electrons, which means that it can form four bonds with other atoms. This is known as tetravalency. The tetravalency of carbon is the reason why it can form such a wide variety of compounds.
Catenation:
Catenation is the ability of an atom to bond to other atoms of the same element. Carbon atoms can bond to each other to form long chains, rings, and other structures. Catenation is another reason why carbon can form such a wide variety of compounds.
Allotropy of carbon:
Allotropy is the ability of an element to exist in different forms with different physical and chemical properties. Carbon exists in three allotropic forms: diamond, graphite, and amorphous carbon.
- Diamond: Diamond is the hardest natural substance on Earth. It is made up of a three-dimensional network of carbon atoms bonded to each other by four single bonds.
- Graphite: Graphite is a soft, slippery substance. It is made up of layers of carbon atoms bonded to each other by three single bonds. The layers are held together by weak van der Waals forces.
- Amorphous carbon: Amorphous carbon is a non-crystalline form of carbon. It includes substances such as charcoal, soot, and coal.
Chemical properties of carbon compounds:
Carbon compounds can undergo a variety of chemical reactions, including:
- Combustion: Combustion is the burning of a substance in the presence of oxygen. Carbon compounds react with oxygen to form carbon dioxide and water.
- Substitution: Substitution reactions involve the replacement of one atom or group of atoms in a molecule with another atom or group of atoms. Carbon compounds can undergo substitution reactions with a variety of different reagents.
- Addition: Addition reactions involve the addition of an atom or group of atoms to a molecule. Carbon compounds can undergo addition reactions with a variety of different reagents.

As we learn more about carbon and its compounds, we are better able to understand and manage our planet’s resources. We can also develop new ways to use carbon to our advantage, while minimizing its negative impacts on the environment.
FAQs on Carbon And Its Compounds:
Q. Why are carbon and its compounds used as fuels? A-> They have a high calorific value. This means that they release a lot of heat when they are burned. They are relatively easy to ignite and burn. They are relatively abundant and inexpensive. They can be transported and stored relatively easily. Q. Why carbon compounds have low melting and boiling point? A-> Carbon compounds have low melting and boiling points because they are held together by weak intermolecular forces, such as van der Waals forces. These forces are much weaker than the ionic bonds that hold ionic compounds together, or the covalent bonds that hold network solids together. As a result, carbon compounds require less energy to melt or boil than other types of compounds.
