The transition metals have a strong tendency to form complaexes because of
(i) smaller sizes of the metal ions
(ii) variable oxidation states
(iii) high ionic charges of metal ions
(iv) availability of vacant d-orbitals for bond formation.

A

(i), (ii), (iii), (iv)

B

(i), (iii), (iv)

C

(iv) only

D

Text Solution

Verified by Experts

The correct Answer is:
B
Complex compounds are those in which the metal ions bind a number of anions or neutral molecules giving complex species with characteristic properties. The transition metals form a large number of complex compounds due to the comparatively smaller sizes of the metal ions, their high ionic charges and the availability of empty d-orbitals for bond formation with the ligands.

Most of the transition metals exhibit (i) paramagnetic behaviour (ii) diamagnetic behaciour (iii) variable oxidation states (iv) formation of coloured ions

Metal carbonyls have the metal ions in zero or unusually lower oxidation states. This is because :

Lithium and beryllium, the first members of alkali metals group and alkaline earth metals group, show anomalous behaviour due to the small sizes of their atoms and ions, high ionisation enthalpies, high polarizing power and absence of vacant d-orbitals in their valence shell. Lithium resembles magnesium while beryllium resembles aluminium due to diagonal relationships. Lithium is the only alkali metal which forms nitride directly. Why?

The colours of the transition metal are due to d-d excitation. The energy required for d-d electron axcitation is available in the visible range. Transition metal ions have the tendency to absorb certain rediations from the visible region and exhibit the complementary colour. The transition metal ions which have completely filled d-orbitals are colourless as the excitation of electron or electrons is not possible within d-orbitals. The transition metal ions which have completely empthy d-orbitals are also colourless. In KMnO_4 and K_2Cr_2O_7 , there are no unpaired electrons at the central atom but they are dep in colour. The colour of these compounds is due to charge transfer spectrum. for example in MnO_4 electron is momentrily transferred from O to the metal and thuys oxygen changes from O^(2-) and O^(ɵ) maganese from Mn^(7+) to Mn^(6+) . Q. Which of the following is paramagnetic as well as coloured ion?
