Chemistry Question on coordination compounds
Identify correct pair of properties of [Co(NH3)6]3+ complex ion.
A
Low spin, diamagnetic
B
High spin, diamagnetic
C
Low spin, paramagnetic
D
High spin, paramagnetic
Answer
Low spin, paramagnetic
Explanation
Solution
The coordination complex [Co(NH3)6]3+ has a d6 electron configuration. It undergoes a low spin arrangement, where the electrons fill the lower energy orbitals before pairing up.
Due to the presence of unpaired electrons, it exhibits paramagnetic behavior.
Therefore, the correct option is (C) Low spin, paramagnetic.
