The correct Answer is:
To analyze the statements regarding CS₂ (carbon disulfide), we can break down the reasoning step by step. ### Step-by-Step Solution: 1. **Understanding the Structure of CS₂:** - Carbon (C) has 4 valence electrons, and each sulfur (S) atom has 6 valence electrons. - In CS₂, carbon forms double bonds with each sulfur atom, resulting in the molecular formula CS₂. 2. **Determining the Shape of CS₂:** - The molecular geometry of CS₂ can be determined using the VSEPR (Valence Shell Electron Pair Repulsion) theory. - Carbon has no lone pairs of electrons, and it forms two double bonds with sulfur. This leads to a linear arrangement of the atoms. - Therefore, the shape of CS₂ is linear. 3. **Polarity of CS₂:** - The polarity of a molecule is determined by its dipole moment, which depends on the difference in electronegativity between the bonded atoms and the molecular geometry. - In CS₂, carbon is less electronegative than sulfur, leading to a dipole moment directed from carbon to sulfur. - However, because CS₂ is linear, the dipole moments from the two C=S bonds are equal in magnitude but opposite in direction. This results in the cancellation of the dipole moments. 4. **Conclusion on Polarity:** - Since the dipole moment of CS₂ is zero due to the linear shape, CS₂ behaves as a non-polar solvent. 5. **Evaluating the Statements:** - **Statement 1:** "CS₂ behaves as a non-polar solvent" - This is true. - **Statement 2:** "The shape of CS₂ is linear" - This is also true. - Furthermore, Statement 2 explains Statement 1, as the linear shape leads to the cancellation of dipole moments, resulting in a non-polar molecule. ### Final Answer: Both statements are true, and Statement 2 provides a correct explanation for Statement 1. Therefore, the correct option is that both statements are true, and Statement 2 explains Statement 1.
