Which statement is true about the most stable Lewis structure for CS2? — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Step 1: Write the Lewis structure of carbon disulfide (CS2). Carbon (Group 14) has 4 valence electrons, and each Sulfur (Group 16) has 6 valence electrons, giving 16 total valence electrons. Step 2: To satisfy the octet of all atoms, Carbon forms double bonds with both Sulfur atoms, represented as S=C=S. This structure gives Carbon 4 bonding pairs (8 valence electrons) and each Sulfur 2 bonding pairs and 2 lone pairs. Step 3: Therefore, all bonds in the most stable Lewis structure of CS2 are double bonds, which corresponds to option (b).
