Understanding Alkynes and Their Reactions

What are the typical transformations performed on alkynes?

• Hydration and oxidation

• Hydration and reduction

• Reduction and polymerization

• Oxidation and polymerization

How does the acidity of a compound change with increasing s-character?

• Acidity increases

• Acidity fluctuates

• Acidity decreases

• Acidity remains the same

Which hybridization state corresponds to the highest acidity?

• None of the above

• sp3

• sp2

• sp

What is the role of acetylide anions in organic synthesis?

• They are used in hydration reactions

• They form carbon-carbon bonds

• They stabilize free radicals

• They act as reducing agents

Why are acetylide anions considered excellent nucleophiles?

• Due to their high pKa value

• Because they are highly acidic

• Because of their linear geometry

• Due to their spherical geometry
