The correct Answer is:
To solve the question of which property hydrogen does not show resemblance with halogens, we will analyze each of the given options step by step. ### Step 1: Analyze Electropositive Character - **Electropositive Character**: Halogens (Group 17 elements) are known for their electronegativity, meaning they tend to gain electrons rather than lose them. They cannot exhibit electropositive behavior, which is the ability to lose electrons and form positive ions. Hydrogen, on the other hand, can exhibit electropositive character under certain conditions (like in metal hydrides). - **Conclusion**: Hydrogen does not resemble halogens in electropositive character. ### Step 2: Analyze Electronegative Character - **Electronegative Character**: Hydrogen can also show electronegativity, although it is less electronegative than halogens. Halogens are highly electronegative and readily attract electrons. Thus, both hydrogen and halogens can exhibit electronegative behavior. - **Conclusion**: Hydrogen resembles halogens in electronegative character. ### Step 3: Analyze Neutral Nature of H₂O - **Neutral Nature of H₂O**: Water (H₂O) is a neutral compound. In contrast, halogens form acidic oxides (e.g., Cl₂O, Br₂O), which are not neutral. This indicates a difference in the nature of their oxides. - **Conclusion**: Hydrogen does not resemble halogens in the neutral nature of H₂O. ### Step 4: Analyze Atomicity - **Atomicity**: Hydrogen exists as H₂ (diatomic), and halogens also exist as diatomic molecules (F₂, Cl₂, Br₂, I₂). Therefore, both hydrogen and halogens have the same atomicity. - **Conclusion**: Hydrogen resembles halogens in atomicity. ### Final Answer Based on the analysis: - Hydrogen does not show resemblance with halogens in: 1. Electropositive character (I) 2. Neutral nature of H₂O (III) Thus, the correct options are I and III.
