In presence of HI, ether oxygen get protonated thus undergo Nucleophilic substitution as nucleophile I- and good leaving group is present. The reaction proceed through SN2 method because it is primary alkyl group.
In presence of NaI, good leaving group is not present hence it will not undergo Nucleophilic substitution reaction.
Since in presence of NaI protonation not takes place thus reaction not occur.

Williamson ether syhthesis involves a SN2 reaction between an alkoxide generated in situ and a primary or secondary halide. Determine the chemical Reaction/Mechanism of the Sn2 reaction: using para-ethyl phenol and 2.5 mL of 25% aqueous NaOH. When the reactant is completely dissolved, add 150 mg of the phase transfer catalyst (tetrabutylammonium bromide) followed by additional of the unknown electrophile, methyl iodide.
