Acid-catalyzed dehydration of secondary and tertiary alcohols proceeds through an E1 mechanism.
Acid-catalyzed dehydration of secondary and tertiary alcohols
proceeds through an E1 mechanism. The first step is the protonation
of the alcohol oxygen to form an oxonium ion. Dehydration of
3-methyl-2-butanol forms one major and two minor organic products.
Draw the structures, including hydrogen atoms, of the three organic
products of this reaction.

The decomposition of XY is second order in XYand has a rate constant of 7.12×10−3 M−1⋅s−1 at a certain temperature. What is the half-life for this reaction at an initial concentration of 0.100 M? How long will it take for the concentration of XY to decrease to 12.5% of its initial concentration when the initial concentration is 0.100 M? How...
