Carbon and Its Compounds Class 10 Notes, Explanation & Important Questions

Carbon and its compounds class 10 is a key CBSE Chemistry chapter that explains how carbon forms a vast number of useful substances through covalent bonding and unique properties. This chapter covers fuels, alcohols, acids, soaps, detergents, and everyday carbon-based materials. These carbon and its compounds class 10 notes simplify reactions, properties, and applications in an exam-focused manner. Understanding carbon and its compounds helps students score well in board exams and build strong fundamentals in organic chemistry.
What Is Carbon?
Carbon and its compounds play a vital role in chemistry because carbon is a unique element capable of forming strong bonds with itself and other elements. Carbon has atomic number 6 and shows catenation, which means it can form long chains and rings.
The properties of carbon class 10 include tetravalency, high bond energy, and the ability to form stable covalent bonds. The importance of carbon class 10 is seen in fuels, medicines, plastics, food, and even DNA. Without carbon, life on Earth would not exist, making it a central topic in organic chemistry.
Covalent Bonding in Carbon Compounds
In carbon and its compounds class 10, most compounds are formed through covalent bonding class 10. Carbon shares electrons instead of losing or gaining them, forming stable covalent bonds. This happens because carbon cannot easily form ions due to its small size and high ionization energy.
Covalent compounds of carbon have low melting and boiling points and do not conduct electricity. Examples include methane (CH₄), ethanol (C₂H₅OH), and ethanoic acid (CH₃COOH). Understanding covalent bonding helps students explain reactions clearly in exams.
Allotropes of Carbon
Carbon and its compounds notes include allotropes, different forms of the same element.
| Allotropes | Structure | Key Property |
| Diamond | 3D network | Hardest substance |
| Graphite | Layered | Good conductor |
| Fullerene | Spherical | Used in nanotech |
These allotropes of carbon class 10, diamond, graphite, fullerene, differ in structure and properties despite being pure carbon.
Properties of Carbon and Its Compounds
These carbon and its compounds class 10 notes cover both physical and chemical properties.
Physical properties of carbon compounds include low melting points, poor electrical conductivity, and insolubility in water.
Chemical properties of carbon compounds include:
- Combustion:
CH₄ + 2O₂ → CO₂ + 2H₂O + Heat
- Oxidation: Alcohols oxidize to acids
- Addition reactions: Seen in unsaturated compounds
- Substitution reactions: Occur in saturated hydrocarbons
These reactions are important for carbon and its compounds class 10 solutions and board exam answers.
Hydrocarbons & Homologous Series
In carbon and its compounds class 10, hydrocarbons are compounds containing only carbon and hydrogen. Hydrocarbons class 10 are of two types:
- Saturated hydrocarbons (alkanes)
- Unsaturated hydrocarbons (alkenes and alkynes)
A homologous series class 10 is a group of organic compounds with the same functional group and similar chemical properties. Members differ by –CH₂– unit and show gradual change in physical properties. This concept helps in identifying reactions easily.
Important Carbon Compounds (Ethanol & Ethanoic Acid)
This section is crucial for carbon and its compounds class 10 solutions.
Ethanol class 10 (C₂H₅OH) is an alcohol used as fuel, solvent, and antiseptic. It reacts with sodium and shows oxidation reactions.
Ethanoic acid class 10 (CH₃COOH) is a weak acid found in vinegar. It reacts with bases and carbonates.
Esterification reaction class 10:
Ethanol + Ethanoic acid → Ester + Water
These reactions are frequently asked in exams and should be memorized.
Soaps and Detergents
In carbon and its compounds class 10, soaps and detergents are cleansing agents. Soaps and detergents class 10 work due to their hydrophilic and hydrophobic parts.
Difference between soap and detergent:
| Basis of Comparison | Soap | Detergent |
| Definition | Soap is a sodium or potassium salt of long-chain fatty acids | Detergent is a sodium salt of sulfonates or sulphates. |
| Raw Materials | Made from natural oils and fats. | Made from petrochemicals. |
| Action in Hard Water | Does not work well in hard water. | Works effectively in hard water. |
| Scum Formation | Forms scum with calcium and magnesium ions. | Does not form scum in hard water. |
| Cleansing Action | Less effective in hard water. | More effective even in hard and acidic water. |
| Biodegradability | Biodegradable and eco-friendly. | Some detergents are non-biodegradable. |
| Use | Used for bathing and washing clothes. | Used for washing clothes and utensils. |
| Examples | Bath soap, washing soap. | Washing powder, liquid detergents. |
