• # question_answer Arrange the following in order of increasing O.N. of iodine: ${{I}_{2}},\,HI,\,HI{{O}_{2}},\,KI{{O}_{3}},\,ICl$

${{\overset{0}{\mathop{I}}\,}_{2}},\,H\overset{-1}{\mathop{I}}\,,\,H\overset{+3}{\mathop{I}}\,{{O}_{2}},\,K\overset{+5}{\mathop{I}}\,{{O}_{3}},\,\overset{+1}{\mathop{I}}\,Cl$ The increasing order is: $HI<{{I}_{2}}<ICl<HI{{O}_{2}}<KI{{O}_{3}}$.
