JEE Main 2026 · 22 January · Evening Shift · Chemistry · p Block Elements (Group 13 & 14)
Given below are two statements : Statement I : Elements ' X ' and '...
Given below are two statements :
Statement I: Elements ' ' and ' ' are the most and least electronegative elements, respectively among \mathrm{X}_{2} \mathrm{O}_{3}\mathrm{Y}_{2} \mathrm{O}_{3}\quad \mathrm{BCl}_{3} and \left[\mathrm{B}\left(\mathrm{H}_{2} \mathrm{O}\right)_{6}\right]^{3+} in aqueous medium.
In the light of the above statements, choose the correct answer from the options given below :

In the light of the above statements, choose the correct answer from the options given below :
Options
- ABoth Statement I and Statement II are false
- BBoth Statement I and Statement II are true
- CStatement I is true but Statement II is false
- DStatement I is false but Statement II is true
Correct answer
C. Statement I is true but Statement II is false
Step-by-step solution
For Statement I:
Among N, As, Sb, P, the electronegativity order is N > P > As > Sb. Thus X = N (most electronegative) and Y = Sb (least electronegative). is acidic (forms HNO₂ with water) is amphoteric (reacts with both acids and bases).
Statement I is true.
For Statement II:
While is covalent and hydrolyzes in water to form , the hydrolysis products are incorrect. In neutral aqueous medium, is formed. The tetrahedral forms only in basic conditions, and boron does not form (boron is not a typical transition metal).
Statement II is false.
