The catalytic activity of transition met...

The catalytic activity of transition metals and their compounds is mainly due to: a)their magnetic behaviour b)their unfilled d-orbitals c)their ability to adopt variable oxidation state d)their chemical reactivity

A

their magnetic behaviour

B

their unfilled d-orbitals

C

their ability to adopt variable oxidation state

D

their chemical reactivity

Text Solution

Verified by Experts

The correct Answer is:
C

Because of the variable oxidation states they may form intermediate compound with one of the reactants. These intermediate provides a riew path with lower activation energy.

A transition element is defined as one which has incompletely filled d - orbitals in its ground state or in any one of its oxidation states Why are Zn Cd and Hg not regarded as transition metals?

Assertion : Zn, Cd and Hg are not considered as transition metals. Reason :d-orbitals in Zn, Cd and Hg are completely filled, both in ground state and in their available oxidation states.

Consider the elements: Cs, Ne, 'F' and 'I'. a) Identify the element that exhibits only negative oxidation state. b) Identify the element that exhibits only positive oxidation state. c) Identify the element that exhibits both poșitive and negative oxidation states. d) Identify the element which exhibits neither the negative nor does the positive oxidation state.

Transition metals show variable oxidation states due to tendency of ‘d’ as well as ‘s’ electrons to take part In bond formation:- Which element in the first series of transition elements does not exhibit variable oxidation states and why?

Transition elements are d-block elements, with some exceptions. Usually they are paramagnetic. They show variable oxidation states. They and their compounds show catalytic property What is the reason for their catalytic property?

Transition elements are d-block elements, with some exceptions. Usually they are paramagnetic. They show variable oxidation states. They and their compounds show catalytic property Zn (atomic number 30) is not a transition element, though it is a d-block element. Why?
