The correct Answer is:
To solve the matching question regarding the concentration processes and their corresponding names, we will analyze each option step by step. ### Step 1: Analyze Option A - Hydrogen on Finely Divided Palladium - **Observation**: When hydrogen gas is absorbed on finely divided palladium, it involves the formation of a solid solution where hydrogen atoms occupy interstitial sites in the palladium lattice. - **Process**: This is known as **Occlusion**, where the gas is trapped within the solid matrix. - **Match**: A matches with 3 (Occlusion). ### Step 2: Analyze Option B - Hydrogen on Nickel - **Observation**: When hydrogen interacts with nickel, especially at elevated temperatures, it forms chemical bonds with the nickel atoms. - **Process**: This process is called **Chemisorption**, where strong chemical bonds are formed between the adsorbate (hydrogen) and the adsorbent (nickel). - **Match**: B matches with 2 (Chemisorption). ### Step 3: Analyze Option C - Hydrogen on Charcoal - **Observation**: When hydrogen is adsorbed on charcoal, the interaction is primarily due to weak van der Waals forces. - **Process**: This type of adsorption is known as **Physisorption**, which involves weak physical interactions. - **Match**: C matches with 1 (Physisorption). ### Final Matching - A matches with 3 (Occlusion) - B matches with 2 (Chemisorption) - C matches with 1 (Physisorption) ### Conclusion The correct matches are: - A - 3 (Occlusion) - B - 2 (Chemisorption) - C - 1 (Physisorption) Thus, the correct answer is option 3: A3, B2, C1. ---

Nitrogen , oxygen and fluorine are the highly electronegative elements. When they are tied to a hydrogen atom to form covalent bond, the electrons of the covalent bond are shifted towards the more electronegative atom.This partially positively charged hydrogen atom forms a bond with the other electronegative atom. This bond is called as hydrogen bond and is weaker than covalent bond.For example, in HF molecule, the hydrogen bond exists between hydrogen atom of one molecule and fluorine atom of another molecule as depicted ---H^(delta+)-F^(delta-)---H^(delta+)-F^(delta-)---H^(delta+)-F^(delta-) Here, hydrogen bond acts as bridge between atoms which holds one atom by covalent bond and the other by hydrogen bond.Hydrogen bond is represented by a dotted line (---) while a solid line represents the covalent bond. Thus, hydrogen bond can be defined as the attractive force which binds hydrogen atom of one molecule with the electronegative atom (F,O and N) of another molecule.
