Question

Arrange the following in the increasing order of the property mentioned. 

(i) HOCl, HClO₂, HClO₃, HClO₄ (Acidic strength) 

(ii) As₂O₃, ClO₂, GeO₃, Ga₂O₃ (Acidity) 

(iii) NH₃, PH₃, AsH₃, SbH₃ (HEH bond angle)

(iv) HF, HCl, HBr, HI (Acidic strength) 

(v) MF, MCl, MBr, MI (ionic character)

Answer 1

(i) Acidic strength: HOCl < HClO₂ < HCIO₃ < HCIO₄

(ii) Acidity: Ga₂O₃ < GeO₂ < AsO₃ < CIO₂

(iii) Bond angle: SbH₃ < AsH₃ < PH₃ < NH₃

(iv) Acidic strength: HF < HCl < HBr < HI

(v) Ionic character: MI< MBr < MCl < MF
