1.	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) onlyD. (i), (iii)
Answer» Correct Answer - 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.
