Which of the following alkynes is symmetrical?

Which of the following alkynes is symmetrical?

Correct Answer: 2-butyne

Step 1: Understand what an alkyne is. Alkynes are hydrocarbons that contain at least one triple bond between carbon atoms.
Step 2: Know what a symmetrical alkyne is. A symmetrical alkyne has the same groups or atoms on both sides of the triple bond.
Step 3: Look at the structure of 2-butyne. It has the formula C4H6 and its structure is CH3-C≡C-CH3.
Step 4: Analyze the structure of 2-butyne. Both sides of the triple bond (C≡C) have the same groups (CH3) attached.
Step 5: Conclude that since both sides are identical, 2-butyne is a symmetrical alkyne.
