Question

Identify the optically inactive compounds from the following
i. trans $- Co ( en )_2 NH _3 Cl ^{2+}$
ii. cis - $Co ( en )_2 Br _2{ }^{+}$
iii. fac $- CoNH _{33} Cl _3$
iv. trans $- CoNH _3 Cl _2{ }^{+}$
v. trans $- CoCl _2 C _2 O _4{ }^{3-}$

Answer 1

i. trans $- Co ( en )_2 NH _3 Cl ^{2+}$
iii. fac $- CoNH _3 Cl _3$
iv. trans $- CoNH _{34} Cl _2{ }^{+}$
v. trans $- CoCl _2 C _2 O _{42}{ }^{3-}$
are optically inactive due to plane of symmetry.
