1. NEET 2026HardProperties of P-Block Elements
   Q1

   The correct statement is:

   • ABoron has a maximum covalency of four
   • BBeryllium has three valence orbitals
   • CMagnesium has a maximum covalency of four
   • DAluminium has five valence orbitals

   Show answer & solution

   Correct answer: (A)

   Boron has maximum covalency of 4 (sp³ hybridization, e.g., [BH₄]^-).
2. NEET 2025Medium
   Q2

   Given below are two statements : Statement I: Like nitrogen that can form ammonia, arsenic can form arsine. Statement II: Antimony cannot form antimony pentoxide. In the light of the above statements, choose the most appropriate answer from the options given below :

   • AStatement I is correct but Statement II is incorrect
   • BStatement I is incorrect but Statement II is correct
   • CBoth Statement I and Statement II are correct
   • DBoth Statement I and Statement II are incorrect

   Show answer & solution

   Correct answer: (A)

   The explanation revolves around the properties and chemical behavior of group 15 elements, specifically nitrogen, arsenic, and antimony. Statement I: This statement is correct. All elements in group 15, including nitrogen and arsenic, can form hydrides with the formula EH₃. For instance, nitrogen forms ammonia (NH₃), and arsenic forms arsine (AsH₃). Statement II: This statement is incorrect. Elements in group 15 are capable of forming two types of oxides: E₂O₃ and E₂O₅. Antimony, being a group 15 element, can indeed form antimony pentoxide (Sb₂O₅).Therefore, Statement I is correct, while Statement II is incorrect.
3. NEET 2023MediumUses of Noble Gases
   Q3

   Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason $R$
   Assertion A: Helium is used to dilute oxygen in diving apparatus. Reason R : Helium has high solubility in $O_2$.
   In the light of the above statements, choose the correct answer from the options given below
   [NEET 2023]

   • ABoth A and R are true and R is NOT the correct explanation of A
   • BA is true but R is false
   • CA is false but R is true
   • DBoth A and R are true and R correct explanation of A

   Show answer & solution

   Correct answer: (A)

   Helium is used as diluent for oxygen in modern diving apparatus because of its very low solubility in blood. Gases diffuses easily with each other.
