Questions & Step-by-Step Solutions
Which of the following is the correct structure for 1-heptyne?
Step 1: Understand that 1-heptyne is an alkyne, which means it has a triple bond between two carbon atoms.
Step 2: Identify that '1-' in 1-heptyne indicates that the triple bond is located between the first and second carbon atoms in the chain.
Step 3: Recognize that heptyne means there are a total of 7 carbon atoms in the chain.
Step 4: Start building the carbon chain: C1 (first carbon) is connected to C2 (second carbon) with a triple bond.
Step 5: Add the remaining carbon atoms (C3, C4, C5, C6, C7) in a straight chain after C2.
Step 6: Add hydrogen atoms to each carbon to satisfy the carbon's bonding requirements, ensuring that the carbons with the triple bond have one hydrogen each.
Step 7: Write the final structure as CH3-CH2-CH2-CH2-CH2-C≡C-H.
