Question Description
Read the passage given below and answer the following questions: In transition elements, generally, ions of the same charge in a given series show progressive decrease in radius with increasing atomic number. This is because the new electron enters a d orbital each time the nuclear charge increases by unity. But the radii of the third (5d) series are virtually the same as those of the corresponding members of the second series. This phenomenon is associated with the intervention of the 4f orbitals which must be filled before the 5d series of elements begin. The filling of 4f before 5d orbital results in a regular decrease in atomic radii called Lanthanoid contraction. In these questions, a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices.Following are the transition metal ions of 3d series: Ti4+, V2+, Mn3+, Cr3+ (Atomic number: Ti = 22, V = 23, Mn = 25, Cr = 24)Assertion (A): Among the given ions, Mn3+ is the most strong oxidizing agent.Reason (R): Mn3+ has an unstable configuration.a)Assertion and reason both are correct statements and reason is correct explanation for assertion.b)Assertion and reason both are correct statements but reason is not correct explanation for assertion.c)Assertion is correct statement but reason is wrong statement.d)Assertion is wrong statement but reason is correct statement.Correct answer is option 'C'.
