Final answer:
CS2 (Carbon disulfide) is nonpolar due to its linear shape and symmetry, which makes the bond polarities cancel out. I2 would be more soluble in CCl4 because they are both nonpolar, whereas H2O is polar and not as effective at dissolving nonpolar substances.
Step-by-step explanation:
The statement 'Cs2 es polar o no polar?' seems to contain a typo, likely the intended compound is CS2 (Carbon disulfide), not Cs which is the chemical symbol for Cesium. Given this clarification, the molecule in question, CS2, is nonpolar. CS2 has a linear molecular shape according to VSEPR theory, with carbon in the middle and sulfur atoms at each end. This symmetric arrangement and the fact that the bond polarities cancel each other out lead to a nonpolar molecule.
In the given example related to solubility, I2 would be more soluble in CCl4 compared to H2O. This is because I2 is a nonpolar molecule and CCl4 is also nonpolar, following the rule that like dissolves like. H2O is a polar solvent, and therefore, does not dissolve nonpolar substances as well.
