Sample questions
-
1.Assertion: Hydrogen bonding leads to higher boiling points in compounds like water. Reason: Hydrogen bonding is a type of strong dipole-dipole attraction that occurs between molecules. (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.
- c.Assertion is false, but reason is true
- d.Assertion is true, but reason is false.

2.Which of the following correctly explains the formation of a single covalent bond with an example?
- A.A single covalent bond is formed by the sharing of one pair of electrons between two atoms, e.g., the hydrogen molecule (H₂).
- B.A single covalent bond is formed by the transfer of one electron from one atom to another, e.g., sodium chloride (NaCl).
- C.A single covalent bond is formed when two atoms share two pairs of electrons, e.g., the oxygen molecule (O₂).
- D.A single covalent bond occurs when one atom donates both electrons in the shared pair, e.g., the ammonium ion (NH₄⁺).
-
3.What is the cause of chemical combination?
- A.The tendency of elements to lose or gain protons to achieve stability.
- B.The tendency of elements to acquire the nearest noble gas configuration in their outermost orbit to achieve stability.
- C.The attraction between oppositely charged ions formed by electron transfer.
- D.The sharing of electrons between metals to form metallic bonds.
-
