NCERT Class 12 Chemistry Chemistry-I 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-I 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.Scuba divers suffer the painful condition known as bends when they rise towards the surface because:
- AThe falling pressure releases dissolved nitrogen as bubbles in the blood, which block the capillaries
- BThe oxygen in the tank is used up faster than the nitrogen
- CThe blood loses its dissolved carbon dioxide too quickly
- DThe rising pressure forces more nitrogen into the blood than the tissues can hold
Q2.A mixture of ethanol and acetone shows positive deviation from Raoult's law because:
- AEthanol and acetone have identical intermolecular forces
- BAcetone forms stronger hydrogen bonds with ethanol than ethanol forms with itself
- CThe two liquids react chemically to give a less volatile product
- DAcetone molecules get in between the hydrogen bonded ethanol molecules and break some of those bonds, so molecules escape more easily
Q3.Among the solvents tabulated in the chapter, the one with the largest molal freezing point depression constant is:
- AEthanol, at 1.99 K kg per mol
- BWater, at 1.86 K kg per mol
- CBenzene, at 5.12 K kg per mol
- DCarbon tetrachloride, at 31.8 K kg per mol
