draw the mechanism for t-butanol in the lucas test
Draw the reaction mechanisms for the Lucas test on ethanol, sec-butanol, and t-butanol with Lucas’s reagent (zinc chloride in concentrated HCl). Draw the reaction mechanisms for the Sodium test on ethanol, sec-butanol, and t-butanol.
Help a) Draw a complete mechanism showing how t-butanol is first converted into an electrophile and then how the electrophile is attached to the aromatic ring. b) What is meant by electron donating and electron withdrawing groups on an aromatic ring? Is the methoxy group an EWG or EDG? Is a t-butyl group an EWG or EDG? c) Two equivalents of t-butanol are used in this reaction. What is the likely problem if only one equivalent of t-butanol is used?...
