Effect of solvent in the reaction of alkyl halide with nitrite ion
Let me first clear out the difference between reaction of alkyl halide with $\ce{AgNO2}$ and $\ce{NaNO2/KNO2}$
The synthesis of nitro compounds from reaction of alkyl halides with alkali metal nitrites using DMSO/DMF as medium is known as the Victor meyer reation($\ce{AgNO2}$) or Kornblum reaction($\ce{NaNO2/KNO2}$). The products of these reaction are generally mixture of nitroalkanes and alkyl nitrites. But the main difference between them is that the % yield of nitroalkane is higher on reaction with $\ce{AgNO2}$ than that of $\ce{NaNO2/KNO2}$.Whereas % yield of alkyl nitrite is higher on reaction with $\ce{NaNO2/KNO2}$ than that of $\ce{AgNO2}$. The required mechanisms for the reactions are..
Now as for the reaction of $\ce{NaNO2/KNO2}$ with alcohol, there is no involvement of alkyl halide. Alkyl nitrite can also be prepared by adding concentrated $\ce{H2SO4}$ to the aqueous solution of $\ce{NaNO2/KNO2}$ and alcohol. The mechanism of this reaction is
