NCERT Class 11 Chemistry Chapter 2 Organic Chemistry – Some Basic Principles and Techniques Test Mock Test
This free online test covers Chapter 2, Organic Chemistry – Some Basic Principles and Techniques, 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.

- BBerzelius isolated urea from the urine of animals
- CWohler synthesised the organic compound urea from the inorganic compound ammonium cyanate
- DKolbe showed that acetic acid occurs naturally in vinegar
Q2.The property of carbon by which it forms covalent bonds with other carbon atoms is called:
- AResonance
- BCatenation
- CHyperconjugation
- DHybridisation
Q3.Which statement about the s character of hybrid orbitals of carbon is correct according to the chapter?
- AAn sp3 hybrid orbital has more s character than an sp orbital and forms the shortest bonds
- BThe s character of a hybrid orbital has no effect on bond length or bond enthalpy
- CAn sp hybrid orbital has more s character than an sp3 orbital, lies closer to the nucleus and forms shorter and stronger bonds, and the greater the s character the greater the electronegativity
- DAn sp2 orbital has more s character than an sp orbital
