Answer: It has a strong affinity for water and removes H and OH as water from other compounds.
- A It has a strong affinity for water and removes H and OH as water from other compounds
- B It is generally classified as a strong acid that largely ionises according to conventional understanding
- C It functions mainly as an oxidising agent in this particular role in routine practice
- D It is largely miscible with water in all proportions overall in most cases under typical conditions
Correct answer: A. It has a strong affinity for water and removes H and OH as water from other compounds
Explanation: Concentrated H<sub>2</sub>SO<sub>4</sub> removes water or elements that form water (H and OH) from compounds like sugar and other organic materials.
Xenon tetrafluoride (XeF4) has six electron domains around xenon — four Xe–F bonds plus two lone pairs. The lone pairs occupy opposite axial positions, leaving the four fluorine atoms in a square-planar shape (Xe–F ≈ 194 pm). Image: ChemSim, Public Domain, via Wikimedia Commons.
Concept context
Covers the nitrogen family (Group 15), oxygen family (Group 16), halogens (Group 17), and noble gases (Group 18). One of the highest-weightage inorganic chapters in NEET and JEE - includes preparation and properties of HNO₃, H₂SO₄, interhalogens, and xenon compounds.
