NEET levelSingle correct optionDifficulty 1 of 3ph060

Complete hydrolysis of $IF X_{5}$ gives

A $HIO$ and $HF$
B $I X_{2}$ and $HOF$
C $H X_{5} IO X_{6}$ and $HF$
D $HIO X_{3}$ and $HF$

Answer: D

The reaction is

IF X_{5} + 3 H X_{2} O HIO X_{3} + 5 HF

. Iodine stays in the +5 state, so the oxyacid is iodic acid;

H X_{5} IO X_{6}

would need iodine in +7, as from

IF X_{7}

.
