Homework Help: Alcohols and an oxidazing agent

  1. Mar 16, 2009 #1

    How many alcohols do not react with [tex] K_2Cr_2O_7 [/tex]? Alcohols have the molecular formula [tex] C_4 H_{10} O.[/tex]

    Attempt at solution

    [tex] K_2Cr_2O_7 [/tex] is an oxidazing agent. The tertiary alcohol cannot be oxidised with it, but you can oxidise secondary alcohols (Source: http://en.wikipedia.org/wiki/Oxidation_of_secondary_alcohols_to_ketones). I think other molecules can be oxidized. So the amount of oxidised alcohols is one.

    Not sure what the question really asks. Perhaps they want you to count all possible alcohols with a given formula and check, how many will be oxidised and how many will not?

    Thanks! I clarified the question. Hopefully, it is now easier to understand.

    The formula indicates that there are no rings or unsaturation. Draw every isomer of this compound and use what you know.
