Question

Consider ${Mg\left(H{CO}_3\right)}_2$ and choose the correct option.

• A. Oxidation state of hydrogen is +5
• B. Oxidation state of carbon is +1
• C. Oxidation state of hydrogen is +1
• D. Oxidation state of hydrogen is +4
• E. None of the above

Answer 1

Answer: (C)

Oxidation state of hydrogen is +1

The oxidation state of carbon is +4.
The oxidation state of hydrogen is +1.
The oxidation state of oxygen is -2.
The oxidation state of magnesium is +2.
Hence, option $\left(C\right)$ is the correct statement.
