    Why is ethanol used as a solvent for NaOH to convert haloalkane to Alkene and why is it used to convert haloalkane to a primary amine??

    If we use water as a solvent we don't get alkenes we get other products.

    But why? That's what I don't really understand is it to do with the solubility in water vs ethanol??

    Polarity is important for solvents. H2O is polar but alkanes arent for example. Polar dissolves in polar, Non-polar the antithesis if im not mistaken

    Ok but, for example, NaOH can react with haloalkanes using ethanol or water as a solvent and they form different products with the different solvent. NaOH is very polar so how does this happen?

    For a reason I don't know (and don't need to know for AS), the ethanol makes the OH in the NaOH act as a base so it takes a hydrogen from the haloalkane, which then forms an alkene.

    If you were to do it with NaOH in water, the OH would act as a nucleophile and just replace the halide.
