Draw the correct structure for each compound. a. 4-octyne b. 3-nonene

Verified step by step guidance

1. Identify the base structure for each compound: For 4-octyne, the base is an 8-carbon chain (octane), and for 3-nonene, the base is a 9-carbon chain (nonane).
2. Determine the type of bond and its position: For 4-octyne, there is a triple bond starting at the 4th carbon. For 3-nonene, there is a double bond starting at the 3rd carbon.
3. Draw the carbon chain for each compound: For 4-octyne, draw a straight chain of 8 carbon atoms. For 3-nonene, draw a straight chain of 9 carbon atoms.
4. Incorporate the multiple bonds: For 4-octyne, replace the single bond between the 4th and 5th carbon with a triple bond. For 3-nonene, replace the single bond between the 3rd and 4th carbon with a double bond.
5. Add hydrogen atoms to satisfy the tetravalency of carbon: Ensure each carbon atom forms four bonds in total by adding the appropriate number of hydrogen atoms to each carbon in both structures.
