Understand the Problem

The question is asking for the correct decreasing order of oxidation states of the central atom in the given compounds: H2O, NH3, and CH4. It presents multiple-choice answers to select from.

Answer

H2O > NH3 > CH4

The correct decreasing order is H2O > NH3 > CH4.

Answer for screen readers

The correct decreasing order is H2O > NH3 > CH4.

More Information

The oxidation state is the hypothetical charge that an atom would have if all bonds to atoms of different elements were fully ionic. Oxygen in water is typically -2, nitrogen in ammonia is -3, and carbon in methane is -4.

Tips

Ensure you correctly determine the oxidation state for each central atom based on its environment in each compound.
