If alkane reacts with iodine to form alkyl iodide then #HI # is also produced as given by the equation.

#RH+I_2rightleftharpoonsRI+HI#
This reaction is reversible one since #HI # possesses reducing property.As a result the alkane is reproduced again and the yield of alkyl iodide is negligible,
But presence of of an oxidizing agent eg #HIO_3# in the reaction mixture oxidizes the #HI# produced to #I_2#and prevents the reaction to occur in backward direction and thus may help the production of RI

Oxidation Of HI
#HIO_3+5HI->3I_2+3H_2O#
