The configuration product that formed in the given reaction has to be predicted. Concept Introduction: Elimination: An atom or group are removed from saturated compound to give unsaturated alkene is known as elimination reaction. In elimination, the removal of halogen ion forms a carbocation followed by removal of hydrogen ion forms an alkene is known as E1 reaction. The abstraction of proton and removal of leaving group takes simultaneously means it is E2 reaction because the rate of reaction depends on both base and substrate.

Question

Acid-catalyzed dehydration of 3,3-dimethyl-2-butanol gives three alkenes: 2,3-dimethyl-2-butene, 3,3-dimethyl- 1-butene, and 2,3-dimethyl-1-butene. Draw the structure of the carbocation intermediate leading to the formation of 2,3-dimethyl-2-butene. • You do not have to consider stereochemistry. • You do not have to explicitly draw H atoms. • If more than one structure fits the description, draw them all. • Separate structures with + signs from the drop-down menu. / H₂C CH₂ CH3 CH3 ChemDoodleⓇ On []

Answer 1

Question

Chapter 9, Problem 9.40P

Interpretation Introduction

Interpretation:

The configuration product that formed in the given reaction has to be predicted.

Concept Introduction:

Elimination:

An atom or group are removed from saturated compound to give unsaturated alkene is known as elimination reaction.

In elimination, the removal of halogen ion forms a carbocation followed by removal of hydrogen ion forms an alkene is known as E1 reaction.

The abstraction of proton and removal of leaving group takes simultaneously means it is E2 reaction because the rate of reaction depends on both base and substrate.

E1 elimination fallows saytzeff rule (more substituted alkene is formed).
