Give the numbers from the reagent table for the
sequence of reactions that will convert ethanol to t-butyl
alcohol.
(2 18 15 18 .... 15 18 ...and
15 9 15 9 are all incorrect)
Homework Answers
The reagents are: 3, 18
Explanation: Oxidation of primary alcohol with Na2Cr2O7, H2SO4 produces carboxylic acid as product. Reaction of carboxylic acid with organolithium reagent produces tertiary alochol as product.
