NCERT Class 11 Chemistry Chapter 3 Hydrocarbons Test Mock Test

This free online test covers Chapter 3, Hydrocarbons, from the NCERT Class 11 Chemistry Part II 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.Alkanes were once called paraffins, from the Latin parum meaning little and affinis meaning affinity, because they:

  • AReact violently with almost every reagent tried on them
  • BHave very little affinity for one another and so cannot form long chains
  • CAre inert under normal conditions and do not react with acids, bases and other reagents
  • DDissolve readily in water because of their small affinity for themselves

Q2.In an alkane the C to C and C to H bond lengths are respectively:

  • A154 pm and 112 pm, with all H-C-H bond angles of 109.5 degrees
  • B154 pm and 112 pm, with all H-C-H bond angles of 120 degrees
  • C133 pm and 120 pm, with all H-C-H bond angles of 180 degrees
  • D112 pm and 154 pm, with all H-C-H bond angles of 109.5 degrees
