What are the two types of dihalides that can be used to synthesize alkynes? Describe the substitution pattern of the two types.

Answer 1

Answer #1

Synthesis of alkyne is based on two alkyl halides.

Both the dihalide undergo E2 mechanism twice in order to get alkyne. Strong base is used to remove the proton from dihalide by E2 mechanism.

First is Geminal dihalide ( Two halogen groups are situated at single carbon)

Second is vicinal dihalide ( Two halogens groups are at two different carbon.)

Lets show their structure and mechanism.

1. Describe properties about alkenes and alkynes. 2. The two stereoisomers of l-bromo-1,2-dichloroethene cannot be designated as cis and trans in the normal way because the double bond is trisubstituted. They can, however, he given (E) and (Z) designations. Write a structural formula for each isomer and give each the proper designation 3. Studies of numerous alkenes reveal a pattern of stabilities that is related to the number of alkyl groups attached to the carbon atoms of the double bond....
