Question

Draw the following organic molecules.
3-Octyne
​

Answer 1

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. In the case of 3-octyne, there is the suffix -yne, which signifies that there is a triple bond (alk yne )

Next, we can add in the triple bond in the 3- position.

Note: Triple bonds are typically drawn as shown in the "re-drawn" structure, but the 3-octyne shown in Step 2 is also correct.
