Which is expected to have the strongest C-O bond? A)CH₃OH B)Cl₂CO C)CF₃CO₂^- D)CO₃^2-

Question

Quizplus · Accepted Answer

The C-O bond strength depends on the electronegativity of the atoms and the size of the atoms. Chlorine is more electronegative than carbon and oxygen and has a small size, leading to a stronger bond with oxygen in option B. In option A, sulfur has a larger size and a lower electronegativity than chlorine, leading to a weaker bond. In option C, fluorine is more electronegative than oxygen, but its smaller size leads to a weaker bond. In option D, the sulfur atom has a lone pair of electrons that can cause repulsion with the oxygen atom, leading to a weaker bond.
