Question : 6
Total: 12
(a) Using Valence Bond theory, predict the hybridization and magnetic character of following:
[ CoF 6 ] 3 − Co = 27 ]
(b) Write IUPAC name of the following complex:
[ CoBr 2 ( en ) 2 ] +
(c) How many ions are produced from the complex[ Co ( NH 3 ) 6 ] Cl 2
(b) Write IUPAC name of the following complex:
(c) How many ions are produced from the complex
Solution:
(a) [ CoF 6 ] 3 −
Hybridization = s p 3 d 2
Magnetic Nature = Paramagnetic
(b)[ CoBr 2 ( en ) 2 ] +
IUPAC name of the complex is Dibromidobis(ethane-1,2 -diamine) cobalt(III) ion.
(c) In aqueous solution of the complex, 3 ions are produced.
[ Co ( NH 3 ) 6 ] Cl 2 ⇌ [ Co ( NH 3 ) 6 ] + 2 + 2 Cl −
(b)
IUPAC name of the complex is Dibromidobis(ethane-1,2 -diamine) cobalt(III) ion.
(c) In aqueous solution of the complex, 3 ions are produced.
