Chapter 22: Hydrocarbons (New Syllabus)

The Class 10 Chemistry Chapter 22 Notes — Hydrocarbons have been freshly uploaded and are now available for free download in PDF format. These notes are prepared strictly according to the new syllabus (2026–27) and are ready to help you revise the chapter quickly before your exams.

Latest Update

As per the latest update in August 2026, these notes have been revised to match the current Punjab Curriculum and Textbook Board (PCTB) syllabus for Chemistry, Class 10. Every heading, definition, structural formula, and question in this chapter has been rechecked against the newest textbook edition so that students preparing for their board exams get 100% accurate and up-to-date material — no outdated content, no missing topics.

We Know You Are Looking for These Notes

If you’re reading this, chances are you’ve already searched “Class 10 Chemistry Chapter 22 notes” more than once today. You’re not alone — thousands of students across Punjab search for this exact chapter every exam season, because Hydrocarbons builds directly on the organic chemistry basics from the last chapter, diving into alkanes, alkenes, and alkynes in a way that can feel overwhelming without clear, side-by-side comparisons. Terms like saturated, unsaturated, and general formulas often get mixed up between the three types without a proper structure to follow. The good news is, you’re just one click away. These notes have been written in simple, exam-friendly language, broken down heading by heading, so that even a student who found catenation and functional groups a bit abstract in the last chapter can confidently classify and compare different hydrocarbons.

Why This Subject Matters

Hydrocarbons are the compounds that power our world — quite literally, since fuels like petrol, diesel, and natural gas are all mixtures of hydrocarbons. Chapter 22 introduces students to the three main families of hydrocarbons — alkanes, alkenes, and alkynes — explaining their general formulas, structures, and the key differences in their chemical behavior, especially around saturation and reactivity. This chapter also touches on important real-world topics like petroleum and fuel combustion, connecting classroom chemistry directly to the energy industry that powers transportation, heating, and countless everyday products.

Short Questions (New Syllabus)

Two-to-three-line answers on core concepts such as the general formulas of alkanes, alkenes, and alkynes, the difference between saturated and unsaturated hydrocarbons, and common uses of petroleum-based fuels — exactly the kind of questions that appear most frequently in board exams.

Long Questions (New Syllabus)

Detailed, exam-length answers explaining topics in depth, such as a complete comparison of alkanes, alkenes, and alkynes with structural formulas, the preparation and properties of key hydrocarbons, and the significance of petroleum as a source of fuel.

Exercise Questions (New Syllabus)

Solved answers to every question given at the end of the chapter in your textbook, so you never have to guess whether your homework answer is correct.
