Homework Help: Preparation of Alkyl Halide from Alcohol

  1. Nov 9, 2006 #1
    Explain why the aqueous washing of your alkyl halide product from the reaction of t-butyl alcohol with concentrated HCL must be carried out quickly.

    Washing the product with aqueous NaOH would get rid of any traces of acid left by neutralizing it, but I don't understand what time has to do with the washings. Can anyone explain this to me?

    Probably to reduce co-precipitation.

    water can act as an acid or a base. If water is left to stand with your t-butyl chloride you can eliminate a small amount, get back your t-butanol and lose some product.
