Question

Which of the following statements are true / false for Tetraamminedithiocyanato-Scobalt(III) chloride :

(i) EAN of central metal is 36

(ii) Ambidented ligand is present

(iii) Bidentate ligand is present

(iv) Complex does not give precipitate with $AgNO_{3}$

TestHub · Accepted Answer

The complex is [ C o ( N H 3 ​ ) 4 ​ ( SCN ) 2 ​ ] Cl (i) EAN = 27 - 3 + (2 x 4) + (2 x 2) = 24 + 8 + 4 = 36. (T) (ii) SCN⁻ is an ambidentate ligand. (T) (iii) NH₃ and SCN⁻ are monodentate. (F) (iv) The chloride ion is outside the coordination sphere, so it will precipitate with A g N O 3 ​ . (F)
