WebBob Mouk’s answer is correct as usual. An interesting twist is that, although one double bond cannot give rise to optical isomerism, two adjacent double bonds can. For instance, consider the molecule 2,3-pentadiene. The terminal methyl groups are at right angles to one another making the molecule chiral.
