Free online mock test for Chemical Bonding (ICSE Class 10 Chemistry) — 20 competency-based questions based on the latest CISCE 2027 syllabus, with instant marking. Try the samples below, then take the full test free.
What to expect: This mock test covers key concepts from the Chemical Bonding chapter — including application-based and competency-focused questions aligned with how ICSE actually sets the paper.
Tip: Attempt without notes first to identify gaps, then review explanations for any wrong answers. Retake after a few days for best retention.
Sample questions
-
1.What is covalency in the context of chemical bonding?
- A.The number of electrons an atom shares to form covalent bonds, e.g., Hydrogen shares 1 in H₂.
- B.The total number of electrons present in the outermost shell of an atom.
- C.The number of ionic bonds an atom can form with other atoms.
- D.The charge acquired by an atom after gaining or losing electrons.
-
2.The type of bond present between hydrogen and chlorine in hydrogen chloride.
- A.Pure Ionic Bond
- B.Pure Covalent Bond
- C.Hydrogen Bond
- D.Metallic Bond
-
3.Assertion: Ionic compounds have high melting points. Reason: Ionic compounds consist of ions held together by strong electrostatic forces. (a) Assertion and reason both are correct statements and reason is the correct explanation of the assertion. (b) Assertion and reason both are correct statements, but reason is not the correct explanation of the assertion. (c) Assertion is false, but reason is true (d) Assertion is true, but reason is false.
- a.Assertion and reason both are correct statements and reason is the correct explanation of the assertion.
- b.Assertion and reason both are correct statements, but reason is not the correct explanation of the assertion.

-
4.Which of the following is a covalent chloride?
- A.Phosphorus Chloride
- B.Potassium Chloride
- C.Magnesium Chloride
- D.Sodium Chloride
-
5.Which of the following sets of conditions correctly describes the formation of an electrovalent bond?
- A.One atom must have high ionization energy, the other must have low electron affinity, and the ions must repel each other.
- B.One atom must easily lose electrons, the other must easily gain electrons, and the resulting ions must have stable electronic configurations with strong electrostatic attraction.
- C.Both atoms must have high ionization energy and low electron affinity, forming shared electron pairs.
- D.The atoms must have identical electronegativities and form neutral molecules without charge separation.
