So, is CS2 polar or nonpolar?
The short answer
is this that CS2 is nonpolar.
And here's why.
We can determine from the Lewis structure
that this is a linear molecule.
All the the atoms are in a line and the bond angle is 180 degrees.
We also can se that it symmetrical, the Sulfur on the left side
is the same in terms of its
configuration with the Sulfur on the
right side.
Because of that
the electrons, those valence electrons, that are
shared between the Sulfur and the
carbon,
those electrons will be distributed
equally around the atom.
That eaual distribution means that
there will  be no polls.
In short ,no polls, no polarity and it's
nonpolar.
Remember polarity results from the
unequal sharing of valence electrons.
In our CS2  molecule
all the electrons are shared equally so
it's nonpolar.
