NCERT Class 10 Science Chapter 4 PDF – Carbon and Its Compounds

Chapter 4 of the NCERT Class 10 Science textbook, Carbon and Its Compounds, is one of the most interesting and scoring chapters in the Chemistry syllabus. It explains the unique behaviour of carbon, its versatile bonding properties, and introduces students to organic chemistry. This chapter covers topics like covalent bonding, hydrocarbons, functional groups, homologous series, and important carbon compounds like ethanol and ethanoic acid. It also explains chemical properties of these compounds and introduces students to the basics of soaps and detergents.

I decided to write about this chapter because many students find it challenging at first, especially when trying to remember different organic reactions and compound structures. But with the right explanation and regular revision, this chapter becomes easy and even enjoyable. Understanding this chapter not only helps in board exams but also builds a strong foundation for higher-level chemistry in Classes 11 and 12. Having a PDF copy of this chapter makes it easier to revise anytime, anywhere. Whether you’re making notes or practising reaction mechanisms, having direct access to the textbook helps a lot. That’s why I’ve made this resource available for all Class 10 students.

Topics Covered in Chapter 4: Carbon and Its Compounds

Here are the key areas covered in the chapter:

  • Introduction to carbon and its tetravalency
  • Covalent bonding in carbon and other elements
  • Saturated and unsaturated carbon compounds
  • Chains, branches, and rings in carbon compounds
  • Homologous series and functional groups
  • Nomenclature of organic compounds
  • Chemical properties of carbon compounds:
    • Combustion
    • Oxidation
    • Addition reactions
    • Substitution reactions
  • Important compounds:
    • Ethanol – properties and uses
    • Ethanoic acid – properties and reactions
  • Soaps and detergents – their formation and cleaning action

Each section includes clear diagrams, examples, and intext activities to reinforce understanding.

Why This Chapter Is Important

  • High-weightage in board exams with both theory and reaction-based questions
  • Builds a foundation for organic chemistry in Classes 11 and 12
  • Helps with lab-based questions and practical understanding
  • Frequently asked in case-based and MCQ formats in the board exam

Many students tend to just memorise the reactions, but it’s better to understand how carbon bonds behave and why these reactions occur the way they do. That’s the kind of clarity NCERT books aim to give.

NCERT Class 11 History Chapter 6 PDF (Hindi): मूल निवासियों का विस्थापन

NCERT Class 11 History Chapter 6 PDF (Hindi): मूल निवासियों का विस्थापन

Chapter 6 of Class 11 History (Hindi Medium), मूल निवासियों का विस्थापन, explores how indigenous communities across Australia, America, and New Zealand were displaced by European settlers. It explains how native populations lived in harmony with nature, practiced unique cultures, and followed their own systems of social organisation long before Europeans arrived. The chapter also describes how colonisation disrupted their lives through land seizure, forced labour, disease, and cultural destruction. It gives a clear picture of how modern nations were built on lands that originally belonged to indigenous people.

While history generally highlights kings, explorers, and governments, this chapter brings us closer to ordinary tribal communities who faced displacement despite being the original inhabitants of their land. Understanding their struggles helps students recognise how colonisation shaped the modern world, and why issues related to indigenous rights, land protection, and cultural preservation are still important today. This chapter encourages empathy and helps readers look at global history from multiple viewpoints, not just from the dominant narratives.

About Chapter 6: मूल निवासियों का विस्थापन

This chapter focuses on the lives of indigenous people before European arrival, the changes brought by colonisation, and the long-term impact on native societies.

Who Were the Indigenous People?

Indigenous groups lived in different parts of the world, such as:

  • Aboriginal communities of Australia
  • Native American tribes
  • Maoris of New Zealand

These communities:

  • Practised hunting, gathering, and small-scale farming
  • Lived close to nature and respected land
  • Passed knowledge orally through stories and songs
  • Had their own law systems and traditions

Arrival of Europeans

From the 16th century onward, European explorers and settlers began occupying lands inhabited by indigenous people. They brought with them:

  • New technologies
  • New religions
  • Weapons
  • Diseases like smallpox and measles

These diseases caused massive population decline among native communities.

How Indigenous People Were Displaced

The chapter explains several ways displacement took place:

  • Land was taken away for farming, mining, and settlements
  • Forced labour systems were introduced
  • Hunting grounds were restricted, affecting food supply
  • Children were separated from families in some regions to “civilise” them
  • Cultural practices were banned or discouraged
