Chemistry - CHEMICAL BONDING Question with Solution | TestHub

(A) OF₂ > OCl₂ > OBr₂ → O–X–O angle decreases with larger X? Actually, OF₂ smallest (~102°), OCl₂ (~111°), OBr₂ (~112°)

(B) CH₃⁺ > CH₄ > CH₃⁻ → CH₃⁺ no lone pairs → largest angle, CH₄ = 109.5°, CH₃⁻ has lone pair → angle smaller

(C) NO₂⁺ > NO₃⁻ > NO₂⁻ → charge affects lone pairs → angle order makes sense

(D) NH₂⁻ > NH₃ > NH₄⁺ → NH₂⁻ has lone pair repulsion → smaller angle
