The EAN of central metal atom in [ Co ( NH ₃ )₆ ] Cl ₃ is [Atomic number of Co =27 ]

Options

  1. A34
  2. B35
  3. C36
  4. D32

Correct answer

C. 36

Step-by-step solution

EAN of central atom in [ Co ( NH ₃ )₆ ] Cl ₃=Z-( ON )+2 ( CN ) where, Z= atomic number ON = oxidation number CN = coordination number ON of Co x+6 0-3=0 x=3 CN =6 EAN =27-3+2 6=36
