JEE Advanced · Chemistry · 9. Redox Reactions
Consider the following molecules : , and . Count the number of atoms existing in their zero oxidation state in each molecule. Their sum is
- A 2
- B 4
- C 6
- D 8
Answer & Solution
Correct Answer
(C) 6
Step-by-step Solution
Detailed explanation
The oxidation number of an atom is zero in a neutral substance that contains atoms of only one element. When same atoms are connected, there is no electronegativity difference, hence, no exchange of electrons. Hence, they have zero oxidation states. The structures of the given molecules are shown below with their oxidation states.
Total atom with zero oxidation number state are .
Total atom with zero oxidation number state are .
