Thank you both!
Well, I know that the cis and trans conformations contribute to distinct physical properties, it's just about electrical conductivity that I'm not sure as yet.
I understand that cis molecules have higher boiling/melting point. The molecule can make stronger bonds on one side only, to usually form dimer like molecules and hence they will clutch together less strongly. While in the trans conformation, the molecule will tend to form chains and make some giant chain and hence, have a lower boiling/melting point.
And KISS, you'll see that there are two types of C-Cl bond shown. They are the means by which chemists show the 3 dimensional bonds in a molecule. A 'dotted' bons represents a bond that protrudes into paper, and a 'bold' bond represents one bond that protrudes out of paper while the normal straight bond represents a bond along the plane of paper.
One thing you caught my attention though.

I was taught that to have optical isomers, there needs to be a carbon molecule with four different groups attached to it. But if we are talking about alkenes, there are only three groups attached to the central carbon atom
Back to the topic.
From my logic, since there is a delocalisation of electrons, both the cis and trans conformations should conduct electricity well... I'll try to draw a picture to illustrate my thoughts.
