How can I draw the skeletal-line structure for 3-octyne?

Question

Ryan Andrews · Accepted Answer

Let's go through this step by step:
First off, when naming compounds, recognize the longest chain of the molecule. For 3-octyne, notice that the word "oct" signifies that the longest chain contains eight carbon atoms. As a first step (Step 1), we can draw out the oct- backbone. Next, we would look for any functional groups that we could add by looking either at the prefixes or the suffixes. In the case of 3-octyne, there is the suffix -yne, which signifies that there is a triple bond (alk yne ). The next step would be to identify where in the oct- backbone the alkyne appears. This info is usually given to us in the form of numbers, 3 in this case. So we can add in the triple bond in the 3- position. This is shown below in Step 2:

undefined To draw the skeletal-line structure for 3-octyne, start with an eight-carbon chain. Then, identify the triple bond, which is located at the third carbon atom from one end of the chain. Finally, add hydrogen atoms to complete the structure, ensuring that each carbon atom has four bonds.
