JEE MainChemistryp Block Elements (Group 15, 16, 17 & 18)

Three p -block elements X , Y , and Z form oxides with the following characteristics: The oxide XO is neutral in nature. The oxide Y ₂ O ₃ is amphoteric in nature. The oxide Z ₂ O ₇ is strongly acidic in nature. The elements X , Y , and Z respectively could be:

Options

  1. AC , Bi , Mn
  2. BN , P , Cl
  3. CS , Sb , I
  4. DN , As , Cl

Correct answer

D. N , As , Cl

Step-by-step solution

The element X forms a neutral oxide XO . Among p -block elements, carbon forms CO and nitrogen forms NO , both of which are neutral. The element Y forms an amphoteric oxide Y ₂ O ₃ . In group 15, arsenic ( As ) and antimony ( Sb ) form amphoteric oxides ( As ₂ O ₃ and Sb ₂ O ₃ ). Phosphorus forms an acidic oxide ( P ₂ O ₃ or P ₄ O ₆ ), while bismuth forms a basic oxide ( Bi ₂ O ₃ ). The element Z forms a strongly acidic oxide Z ₂ O ₇ . This corresponds to a halogen in the +7 oxidation state, such as chlorine formin
