Question

Match the LIST-I with LIST-II 

LIST-I (Bonds)	LIST-II (Formations)
A. Ionic Bonds	Actual transfer of electrons from one atom to another atom
B. Metallic Bonds	Partial sharing of valence electrons by the neighboring atoms
C. Van der Waals Bonds	This type of bonding arises from dipolar interaction of crystals/molecules of the crystal.
D. Hydrogen Bonds	This type of interaction between the oppositely charged ends of permanently polarized molecules.

Choose the correct answer from the options given below:

• A. A - I, B - II, C - III, D - IV
• B. A - II, B - I, C - IV, D - III
• C. A - I, B - II, C - IV, D - III
• D. A - III, B - IV, C - I, D - II

Hint:

To solve matching questions, start with the most distinct and unambiguous pairs. Here, "Ionic Bonds" and "Actual transfer of electrons" (A-II) is a very clear match. This can help eliminate incorrect options quickly. Then match the next clearest pair, like Hydrogen Bonds (D-III).

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
This question requires matching different types of chemical bonds with their correct descriptions.
Step 2: Detailed Explanation:
A. Ionic Bonds: These are formed by the electrostatic attraction between oppositely charged ions. This happens through the complete transfer of one or more electrons from one atom to another. This matches description II.
B. Metallic Bonds: This type of bonding involves a 'sea' of delocalized electrons that are shared among a lattice of positive metal ions. Description I, "Partial sharing of valence electrons by the neighboring atoms," is the closest available description, though it more accurately describes covalent bonding. In the context of the given options, metallic bonding is a form of electron sharing.
C. Van der Waals Bonds: These are weak, secondary bonds that arise from temporary or permanent dipoles in atoms or molecules. They are a general category of dipolar interactions. Description IV, "This type of bonding arises from dipolar interaction of crystals/molecules of the crystal," is a suitable general description for these forces.
D. Hydrogen Bonds: This is a special, strong type of dipole-dipole interaction. It occurs when a hydrogen atom is bonded to a highly electronegative atom (like N, O, or F) and is attracted to another electronegative atom nearby. This corresponds to an interaction between permanently polarized molecules. This perfectly matches description III.
Step 3: Final Answer:
The correct matching is:

A \(\rightarrow\) II
B \(\rightarrow\) I
C \(\rightarrow\) IV
D \(\rightarrow\) III
This corresponds to option (B).
