Elimination Reactions of Haloalkanes

Question 1

What is the product of an elimination reaction of a haloalkane?

Answer 1

An alkene.

Question 2

What is needed to form an alkene from a haloalkane?

Answer 2

Ethanoilic OH- ions (hydroxide dissolved in ethanol)

Question 3

What do the OH- ions in elimination reactions act as?

Answer 3

A base. It attacks a proton instead of a delta positive carbon like in nucleophilic substitution

Question 4

What hydrogen is attacked in an elimination reaction?

Answer 4

The hydrogen of the carbon bonded to the halogen carbon

Question 5

Why are the elimination reactions of haloalkanes useful in industry?

Answer 5

Because alkenes are useful for making many types of polymers. Elimination reactions mean they can be produced without using crude oil (fossil fuels).

Question 6

When does an elimination reaction form isomers?

Answer 6

When the halogen of the haloalkane is on a middle carbon. The hydroxide can attack 2 different hydrogens, changing the location of the double bond. This is positional and geometric isomerism
