CSIR UGC NET Dec15 Q.5

Vishnu Mestry Monday, 10 October 2016 No Comments
The W-W bond order in [W(η5 -C5H5)(μ- Cl)(CO)2]2 is 


A. three
B. Two
C. one
D. Zero

Ans: 
To calculate bond order
(a) Calculate TVE : a
(b) Calculate n x 18 : b [n = number of metal]
(c) Calculate 𝑏−𝑎/2 = [number of M-M bond]


[W(η5 -C5H5)(μ- Cl)(CO)2]2

(a) TVE = 36 [12 + 10 + 6 + 8] = a
(b) n x 18 = 2 x 18 = 36 = b
(c) 𝑏−𝑎/2 = 36−36 2 = 0 

Ans - D. Zero
