Question

The $EAN$ value $y \left[Ti\left(\sigma-C_{6}H_{5}\right)_{2}\left(\pi-C_{5}H_{5}\right)_{2}\right]^{0}$ is

• A. $32$
• B. $33$
• C. $34$
• D. $35$

Answer 1

Answer: (C)

$34$

Answer 2

$EAN$ = Atomic number of central atom
- (oxidation state + electron gained by ligand)
Atomic number of $Ti = 22$
Contribution by $\left(\sigma-C_{6}H_{5}\right)=1e^{-}$
Contribution by $(\pi -C_{5}H_{5})=5e^{-}$
$\therefore EAN =22-0+(1\times 2)+(2\times 5)$
$y=34$
