Lesson: Alkynes Chemistry

In this lesson, we will learn how to name and describe the reactions of alkynes.

Lesson Plan

Students will be able to

describe the homologous series of alkynes,
name different alkyne molecules and explain their physical properties,
describe the preparation of alkynes in the laboratory and on an industrial scale,
explain common addition reactions of alkynes.

Q1:

Which of the following combinations describes the triple bond in an alkyne group?

Q2:

Reactions of ethyne are often catalyzed to ensure a more complete reaction and greater yield.

Which of the following can be used as a catalyst in the hydrogenation reaction of ethyne to form ethane?

Which of the following can be used as a catalyst in the addition reaction of ethyne and water to form ethanal?

Q3:

What is the major product of the reaction when ethyne gas is bubbled through a solution of bromine water, which is decolorized in the process?
