Verified By Collegedunia
The Correct Option is C
Solution and Explanation
$EAN$ = 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 $(\pi -C_{5}H_{5})=5e^{-}$
$\therefore EAN =22-0+(1\times 2)+(2\times 5)$
$y=34$
- (oxidation state + electron gained by ligand)
Atomic number of $Ti = 22$
Contribution by $\left(\sigma-C_{6}H_{5}\right)=1e^{-}$
Contribution by $(\pi -C_{5}H_{5})=5e^{-}$
$\therefore EAN =22-0+(1\times 2)+(2\times 5)$
$y=34$

Concepts Used:
Coordination Compounds
A coordination compound holds a central metal atom or ion surrounded by various oppositely charged ions or neutral molecules. These molecules or ions are re-bonded to the metal atom or ion by a coordinate bond.
Coordination entity:
A coordination entity composes of a central metal atom or ion bonded to a fixed number of ions or molecules.
Ligands:
A molecule, ion, or group which is bonded to the metal atom or ion in a complex or coordination compound by a coordinate bond is commonly called a ligand. It may be either neutral, positively, or negatively charged.
