Question

Arrange the following in order of property mentioned against each: 

(i) BaCl₂, MgCl₂,BeCl₂, CaCl₂ (Increasing ionic character) 

(ii) Mg(OH)₂, Sr(OH)₂, Ba(OH)₂, Ca(OH)₂ (Increasing solubility in water) 

(iii) BeO, MgO, BaO, CaO (increasing basic strength)

Answer 1

(i) Increasing order of ionic character is-

BeCl₂ < MgCl₂ < CaCl₂ < BaCl₂

(ii) Increasing order of solubility in water-

Mg(OH)₂ < Ca(OH)₂ < Sr(OH)₂ < Ba(OH)₂

(iii) Increasing order of basic strength-

BeO < MgO < CaO < BaO
