NCERT Class 10 Science Chapter 4 Carbon and its Compounds Test Mock Test
This free online test covers Chapter 4, Carbon and its Compounds, from the NCERT Class 10 Science textbook. The 30 questions are written directly from the chapter — definitions, processes, worked examples and the points the book italicises — so a score here tells you how much of the chapter actually stuck, not how well you guess. Each answer carries an explanation that says why the right option is right and why the other three fail, which is where most of the learning happens. Attempt it after your first read of the chapter, then again before the exam. There is no negative marking, and you can review the full solution the moment you submit.

Sample Questions
Q1.The share of carbon in nature given at the start of the chapter is:
- A2 per cent of the earth's crust as minerals and 3 per cent of the atmosphere as carbon dioxide
- B0.02 per cent of the earth's crust as minerals and 0.03 per cent of the atmosphere as carbon dioxide
- C0.03 per cent of the earth's crust as minerals and 0.02 per cent of the atmosphere as carbon dioxide
- D0.2 per cent of the earth's crust as minerals and 0.3 per cent of the atmosphere as carbon dioxide
Q2.Carbon does not form ions by gaining or losing four electrons because:
- AA nucleus with six protons could not hold ten electrons, and removing four electrons would need a very large amount of energy
- BCarbon already has a completely filled outermost shell like a noble gas
- CCarbon atoms are too large for the nucleus to influence the outermost electrons
- DCarbon has only two electrons in its outermost shell, so it needs to share only two
Q3.A covalent bond is formed when:
- AOne atom transfers electrons completely to another atom
- BTwo atoms are held together by the attraction between a positive and a negative ion
- CA pair of electrons is shared between two atoms so that both attain a filled outermost shell
- DA metal loses electrons to a non-metal, forming oppositely charged ions
