Carbon and hydrogen usually bonds in one of three ways: single bonds (-), double bonds (=), and triple bonds (≡). In this article, we will feature only single and double carbon-to-carbon bonds… two single and three double. The compound is 1,3,5-hexatriene. Notice the featured image (above) that illustrates the most common way it is drawn.
There is another way to draw 1,3,5-hexatriene. It represents a second form, an isomer1, of the first form. We present a drawing of it, as well, to the right. Notice, however, it is drawn twice. Once illustrating two hydrogen atoms relevant to our discussion. The two isomers differ somewhat in chemical behavior.
We now present, once again, our first isomer of 1,3,5-Hexatriene… this time with its relevant hydrogen atoms. We’ll call it Isomer I. Notice in this drawing, the two hydrogen atoms appear on opposite sides of the (3,4) double bond. Isomer II (for we now so call it) had both hydrogen atoms on the same side of the (3,4) double bond. Because of the di...
The use of cis and trans, even though I just introduced it, has largely lost favor, being replaced by other notation (for reasons we won’t discuss). It should be noted that the old-school terminology is dying slowly. The new notation is the accepted IUPAC2official notation.
Rather than read about the new notation, we figured a video would be an invigorating change. We here embed a Khan Academyvideo (4:55) for your enjoyment.
So the names of these two isomers are: (E)-1,3,5-hexatriene and (Z)-1,3,5-hexatriene As you might imagine, the fun begins when there is a longer carbon chain containing more double bonds. As a simple example, consider the molecule seen at right. Considering the 2nd, 3rd and 4th double bonds’ configuration possibilities, how many alkene isomers do y...
