NCERT Class 12 Chemistry Chemistry-II Full Book Test Mock Test
This full-book test draws 25 questions from every one of the 5 chapters in the NCERT Class 12 Chemistry-II textbook, in chapter order. Chapter tests tell you whether you remember a chapter you have just read; this one tells you what survives once the whole book is behind you, which is the harder and more useful question. Every item is set from the book text and carries a full explanation, so a wrong answer points you back to the exact chapter to revise. Use it as a revision check before school exams, or as a base-building drill if you are preparing for UPSC, SSC or a state PCS, where NCERT is the standard starting text. No negative marking.

Sample Questions
Q1.In electrophilic substitution reactions of haloarenes, the halogen atom is:
- ANeither activating nor deactivating, since its two effects exactly cancel
- BDeactivating and meta directing, because both its effects withdraw electron density from the ring
- CSlightly deactivating but ortho and para directing, because its inductive effect withdraws electrons while its resonance effect raises the electron density at those positions
- DStrongly activating and meta directing, because its resonance effect dominates the inductive effect
Q2.Haloarenes are extremely unreactive towards nucleophilic substitution. Which reason is given in the chapter?
- AThe phenyl cation formed by self-ionisation is strongly stabilised by resonance
- BNucleophiles are electron deficient and so cannot approach an electron rich ring
- CThe halogen lone pairs conjugate with the ring, giving the C-X bond partial double bond character that is harder to break
- DThe halogen atom in a haloarene is attached to an sp3 hybridised carbon with little s-character
Q3.From the values tabulated for the carbon-halogen bond, going from CH3-F to CH3-I:
- ABoth the bond length and the bond enthalpy stay almost constant
- BThe bond length falls from 214 to 139 pm while the bond enthalpy rises from 234 to 452 kJ per mol
- CThe bond length increases from 139 to 214 pm while the bond enthalpy falls from 452 to 234 kJ per mol
- DBoth the bond length and the bond enthalpy increase steadily
