Question

What is the reaction of 3,4 dimethyl-1-pentyne with ozone, followed by the reaction with solid Zn in an acid medium?

a) Ozonolysis
b) Hydrogenation
c) Halogenation
d) Reduction

Answer 1

The reaction of 3,4 dimethyl-1-pentyne with ozone, followed by the reaction with solid Zn in an acid medium is called ozonolysis. Ozone oxidizes the carbon-carbon triple bond in the alkyne, forming an ozonide intermediate, which is then reduced by Zn in an acid medium.

Step-by-step explanation:

The reaction of 3,4 dimethyl-1-pentyne with ozone, followed by the reaction with solid Zn in an acid medium is called ozonolysis. Ozone can oxidize the carbon-carbon triple bond in the alkyne, resulting in the formation of an ozonide intermediate. This intermediate can then be reduced by Zn in an acid medium, leading to the formation of aldehydes or ketones.
