NEETChemistryP Block ElementsMCQ+4 / −1

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 :

  1. A
    Statement I is correct but Statement II is incorrect
  2. B
    Statement I is incorrect but Statement II is correct
  3. C
    Both Statement I and Statement II are correct
  4. D
    Both Statement I and Statement II are incorrect
View written solutionFree

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.
