CO2 vs CS2

[Isis_DW_3G]

why is CO2 more ionic than CS2?

[Lea Chamoun 2J]

CO2 is more ionic because C and O have a greater electronegativity difference than C and S. The greater the electronegativity difference between the atoms in the molecule, the more ionic their character. C and S have around the same electronegativity value, which can be found in Figure 2D.2 in the textbook, meaning their electronegativity difference is going to be low and it is more covalent.

[Vanessa Perez]

By comparing the electronegativity, you can determine which bond is more ionic. As Lea said. Also distance has an effect on ionic character

[Edwin Liang 1I]

It is because the oxygen is much more electronegative

Hey!
Just to add on, it is important to note the periodic trends that we have been going over. When comparing O and S, we can see that O would have a smaller atomic radius. This means that it would have a stronger electronegativity, since its protons can hold on to its electrons better due to less shielding. With this, we can note the electronegativity difference being higher between C and O than C and S. With this, since the electronegativity difference is higher, we can assume that it has more ionic character. I hope this helps!

CO2 because the oxygen is more electronegative

[CesarLec1]

Sulfur is less electronegative than oxygen so it puts up "less of a fight" than the oxygens which makes the dipole moments weaker than the CO2

Would it be that the greater the difference in electronegativity, the more ionic a molecule can be?

[Arnav Saud 2C]

The difference in electro negativity between the carbon and oxygen is greater than it is between the sulfur and carbon
