Which of the following sequence is correct with reference to the oxidation number of iodine?

Options

A. `I_(2) gt Icl lt HI lt HIO_(4)`
B. `HIO_(4) lt IC l lt I_(2) HI`
C. `I_(2) lt HI lt IC l lt HIO_(4)`
D. `HI lt I_(2) lt IC l lt HIO_(4)`

Answer

D

Explanation

Oxidation numbers of I an be calculated as:
`{:("In HI","In "I_(2)," In ICl","In "HIO_(4)),(1+x=0,x=0,x-1=0,1+x+[2xx(-4)]),(1+0x-8=0,,,),(x=-1,,x=1,thereforex=+7):}`
`therefore HI lt I_(2) lt ICl lt HIO_(4)`
