Lesser number of oxidation states at the...

Lesser number of oxidation states at the extreme ends of the transition series, stems from:

A

too few electrons to lose or share

B

too many d electrons for higher valence

C

greatest number of oxidation states for manganese +2 to +7

D

presence of filled f-orbitals.

Text Solution

Verified by Experts

The correct Answer is:
A, B
(a), `Sc,Ti` (b). Hence fewer orbitals available in which to share electrons with other (Cu,Zn).
