drag the tiles to the correct locations. each tile can be used more than once, but not all tiles will be used. one or more locations will remain empty. carbonyl sulfide has the chemical formula cos. carbon has four valence electrons, and oxygen and sulfur each have six valence electrons. complete the lewis structure for this covalent compound.
Answer
Explanation:
Step1: Determine the central atom
Carbon is the central atom as it has the lowest electronegativity among C, O, and S.
Step2: Calculate total valence - electrons
Carbon has 4 valence electrons, oxygen has 6, and sulfur has 6. So, (4 + 6+6=16) valence electrons.
Step3: Form single - bonds first
Connect carbon to oxygen and carbon to sulfur with single - bonds. This uses 4 electrons ((2\times2)).
Step4: Distribute remaining electrons
We have (16 - 4 = 12) electrons left. Place 3 lone - pairs on oxygen and 3 lone - pairs on sulfur to satisfy the octet rule for O and S. But this gives C only 4 electrons.
Step5: Convert lone - pairs to double - bonds
To satisfy the octet rule for carbon, we convert one lone - pair from oxygen and one lone - pair from sulfur into double - bonds. The Lewis structure is (O = C = S), with two lone - pairs on oxygen and two lone - pairs on sulfur.
Answer:
From left to right in the structure: (O), (=), (C), (=), (S), with two sets of two dots ((\bullet\bullet)) above and below (O) and two sets of two dots ((\bullet\bullet)) above and below (S).
