NEET Chemistry Oxidation Number Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 11
Assertion (A): The sum of oxidation numbers of all atoms in a polyatomic ion must equal the charge on the ion. | Reason (R): The oxidation number of a nonmetallic element in its compounds can be either positive or negative.
A
Both A and R are true, and R is the correct explanation of A.
B
Both A and R are true, but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false.
Correct Answer
Option B
Detailed Explanation
The assertion and reason are both true. However, the reason does not explain the assertion directly as it discusses the oxidation number of nonmetals in general, not specifically how they sum up to the charge in a polyatomic ion.
