NEET Chemistry Transition Elements Assertion Reason Question
Type: Assertion Reason-assertion-Medium-Class 12
Assertion (A): Transition metals have variable oxidation states. | Reason (R): The d orbitals in transition elements are completely filled in their ground state.
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, but (R) is true.
Correct Answer
Option C
