Question

Which one the following has largest number of isomers? (R -= alkyl group, en = ethylenediamine) (A) [Ru(NH3)4Cl2 +] (B) [Co(en)2Cl2]+ (C) Ir(PR3)2 H(CO)]2+ (D) [Co(NH3)5Cl]2+

[ Co ( en )2 C 12]+has largest number of isomers which includes geometrical isomers (cis and trans isomers) as well as stereoisomers (d form, l form and optically inactive form). en is a bidentate ligand.

Q. Which one the following has largest number of isomers?
(R -= alkyl group, en = ethylenediamine)

$[R u (N H_{3})_{4} C l_{2}^{+}]$

$[C o (e n)_{2} C l_{2}]^{+}$

$I r (P R_{3})_{2} H (CO)]^{2 +}$

$[C o (N H_{3})_{5} Cl]^{2 +}$

$[C o (e n)_{2} C 1_{2}]^{+}$ has largest number of isomers which includes geometrical isomers (cis and trans isomers) as well as stereoisomers (d form, l form and optically inactive form). en is a bidentate ligand.
