Vedclass · Answer

(D) To determine the correct sequence,calculate the oxidation number of iodine in each compound:$1$. In $HI$,the oxidation state of $I$ is $-1$.$2$. In $I_2$,the oxidation state of $I$ is $0$.$3$. In $ICl$,since $Cl$ is more electronegative than $I$,the oxidation state of $I$ is $+1$.$4$. In $HIO_4$,let the oxidation state of $I$ be $x$. Then $1 + x + 4(-2) = 0$,which gives $x = +7$.Comparing these values: $-1 Therefore,the correct sequence is $HI < I_2 < ICl < HIO_4$.
