Question

Oxidation is a process that involves:

• A. addition of oxygen
• B. removal of oxygen
• C. addition of hydrogen
• D. removal of hydrogen

Answer 1

Answer: (A), (D)

removal of hydrogen

Explanation for correct options

(a) addition of oxygen

1. Oxidation is the chemical process in which involves the addition of oxygen atom to the molecules and the removal of hydrogen atom from the molecules.
2. Example of oxidation in which carbon reacts with oxygen to form carbon dioxide C+O₂⇢CO₂
3. hence the correct option.

(d) removal of hydrogen

1. The removal of hydrogen atom from the molecules is also known as Oxidation.
2. Example of oxidation : H₂S+Br₂⇢2HBr+S ,Where Hydrogen sulfide get oxidize to Sulphur.
3. hence the correct option

(b) removal of oxygen

1. By definition ,Oxidation process involves the addition of oxygen atom to the molecules.
2. hence the incorrect option.

(c) addition of hydrogen

1. According to the general definition, Oxidation process involves the removal of the hydrogen atom from the molecules.
2. hence the incorrect option

Therefore ,Oxidation is a process that involves (a) addition of oxygen and (d) removal of hydrogen
