Detailed Solution for Minor Test - Inorganic Chemistry - Question 5

Nd3+ ions shows strong absorption in yellow region hence used by glassblowers.

Minor Test - Inorganic Chemistry - Question 6

Select Correct Statement from following regarding t-block elements
(i) A bsorption spectrum of lanthanoids(III) is largely dependent on nature of ligands.
(ii) Magnetic moments of lanthanoids (III) is generally greater than corresponding actinides (III)
(iii) Spectra of Heavier actinides (III) ions show resemblance with lanthanoids (III) ions
(iv) Ce3+ ion is colourless in aqueous medium.
The correct answer is

Detailed Solution for Minor Test - Inorganic Chemistry - Question 6

Due to deep buried nature of 4f orbitals, spectrum is largely independent on nature of ligands.
Due to some orbital quenching in case of actinoids. magnetic moment is less as compared to Lanthanoids.
Due to poor exposure of 5f-orbitals in heavier actinoids. their spectrum is similar to that of Lanthanoids Ce3+ show f-d transition which lies in UV region hence colourless.
