  • $\begingroup$ I redrawn your structure using free LaTeX package chemfig based on your comment and previous attempt to format it using source code markup tool. There are also numerous free GUI tools such as MarvinSketch to draw molecules if you cannot reach the wanted representation with ASCII graphics (which is understandable). $\endgroup$ – andselisk Jul 23 at 4:16

    $\begingroup$ Also, for the reference, see How to ask and answer nomenclature questions?. I think there is a very similar question asked before, but I'm unable to find it for now; probably other users could help. $\endgroup$ – andselisk Jul 23 at 4:18

2,3-Dichloropent-2-ene

Explanation: The longest carbon chain is a 5 membered chain with carbon-carbon double bond. Since double bond must be given the least locant, we number it from the leftmost carbon as in your image. The substituents are named accordingly by indicating their positions.
