Topic & Syllabus Coverage

521+ words · 6 topics covered

The Class 11 Chemistry Topic-wise Practice mock test is a focused practice paper for Class 11 students who are preparing for Class 11 Chemistry. It follows the Topic-wise format and uses a mixed difficulty mix, so a student can practise the same style of questions that appears in school tests, scholarship exams and competitive entrance papers. The paper contains 20 questions and runs for 20 min. Each correct answer adds 1 mark and there is no negative marking.

The syllabus coverage is built around 6 main topics: Classification of matter, Empirical formula, Stoichiometry, Mole concept, Balancing, Molecular mass. Every question is written to test understanding rather than simple recall. Definitions, formulae, units, diagrams, examples and common exceptions are combined so that the student has to read the question carefully, choose the correct concept and apply it in a slightly new situation. This is the same skill that a real exam expects, where two options may look similar and only one satisfies every condition in the question.

A good way to use this paper is to revise the chapter first, then attempt the test in one sitting without notes. The 20 min limit is deliberately short enough to build speed but long enough to reward careful reading. Students should keep a rough sheet for calculations, mark doubtful questions for review and avoid spending too long on a single item. After submission, the detailed solutions should be read even for correct answers, because the explanation often shows a faster method or points out a trap that can appear in another form later.

The topic list is also a revision checklist. If a topic feels unfamiliar, go back to the textbook, revise the formula or definition, and then attempt the same test again after a day or two. Repeated practice on Class 11 Chemistry helps students recognise the wording used by examiners, improves calculation speed and reduces careless mistakes. For formula-based questions, write the formula before substituting values; for concept-based questions, underline the limiting words such as "not", "always", "only" and "except"; for data or diagram questions, read the labels and units before choosing an option.

This page is public and does not require a login. Five sample questions with the correct answer and a detailed explanation are shown below so that students, parents and teachers can judge the quality of the paper before starting. A guest can also attempt the full timed test without creating an account. Guest attempts are intentionally kept only in the browser and are not added to a database scoreboard. Students who sign in get a saved scoreboard, topic-wise analysis, attempt history and recommendations for the next test.

The final revision plan is simple: complete the chapter, read the formulae and key definitions, attempt this Class 11 Chemistry Topic-wise Practice paper, review every explanation, note the weak topics and repeat a mixed or level-wise test after revision. Use the score, accuracy and time report to decide whether the next step should be more concept revision, more speed practice or a full-length paper. This cycle turns a single mock test into a complete learning session instead of a one-time score.

These are real questions from this paper. The correct answer and detailed explanation are shown openly so you can check the quality before starting the full test.

Free · no login
1Classification of matterEASY

Which of these is a homogeneous mixture?

ASand and water
BSalt solutionCorrect
COil and water
DAir and dust
Correct answer

Salt solution

Step-by-step explanation

A salt solution has a uniform composition throughout, so it is homogeneous.

2Empirical formulaHARD

The empirical formula of a compound with 40% C, 6.7% H and 53.3% O is:

ACH₂OCorrect
BC₂H₄O
CCHO
DC₂H₆O
Correct answer

CH₂O

Step-by-step explanation

Moles: C = 40/12 = 3.33, H = 6.7/1 = 6.7, O = 53.3/16 = 3.33. Ratio 1:2:1, so CH₂O.

3StoichiometryMEDIUM

The limiting reagent in a reaction is the reactant that:

AIs present in excess
BIs completely consumed firstCorrect
CHas the largest mass
DHas the highest molar mass
Correct answer

Is completely consumed first

Step-by-step explanation

The limiting reagent is used up first and decides the amount of product formed.

4Mole conceptEASY

At STP, 22.4 L of any ideal gas contains:

A1 moleCorrect
B0.5 mole
C2 moles
D22.4 moles
Correct answer

1 mole

Step-by-step explanation

Molar volume of an ideal gas at STP is 22.4 L, which contains one mole.

5BalancingEASY

Which quantity is conserved in a balanced chemical equation?

AMoles of reactants
BMassCorrect
CVolume
DNumber of molecules
Correct answer

Mass

Step-by-step explanation

A balanced equation conserves the number of atoms of each element, and hence mass.
