JEE Main 2026 — p Block Elements (Group 13 & 14) Question with Solution
JEE Main 2026 (22 January Shift 2)
Question
Given below are two statements :
Statement I: Elements ' ' and ' ' are the most and least electronegative elements, respectively among and P. The nature of the oxides and is acidic and amphoteric, respectively.
Statement II : is covalent in nature and gets hydrolysed in water. It produces and in aqueous medium.
In the light of the above statements, choose the correct answer from the options given below :

Correct answer
CStatement I is true but Statement II is false
Step-by-step explanation
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) and 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.
