Questions & Step-by-Step Solutions
Which of the following compounds is an example of a terminal alkyne?
Step 1: Understand what an alkyne is. An alkyne is a type of hydrocarbon that contains at least one triple bond between carbon atoms.
Step 2: Know the difference between terminal and internal alkynes. A terminal alkyne has the triple bond at the end of the carbon chain, while an internal alkyne has the triple bond between two carbon atoms.
Step 3: Look at the compound 1-butyne. It has the structure CH≡C-CH2-CH3.
Step 4: Identify the position of the triple bond in 1-butyne. The triple bond (≡) is between the first carbon (C1) and the second carbon (C2).
Step 5: Determine if 1-butyne is a terminal alkyne. Since the triple bond is at the end of the carbon chain (C1), 1-butyne is indeed a terminal alkyne.
