Option showing correct order of bond angles is/are ( $M =$ central atom, $X =$ Surrounding atom)

Answer:

B, D

Solution:

(A) PCl₄⁺ < PBr₄⁺ < PI₄⁺ → bond angles decrease with larger substituents → (PCl₄⁺ largest angle)

(B) XeO₄ = SiCl₄ = SO₄²⁻ → tetrahedral, all bond angles = 109.5°

(C) NH₄⁺ < NH₃ < NH₂⁻ → lone pair repulsion decreases bond angle → NH₂⁻ < NH₃ < NH₄⁺

(D) NH₃ > PH₃ > AsH₃ → bond angle decreases with bigger central atom → Correct
