The type(s) of isomerism exhibited by the K[Cr(H2O)2(C2O4)2] complexes is:
1. Geometrical isomerism
2. Optical isomerism
3. Linkage isomerism
4. Both 1 and 2
Statement I: | [Ni(CN)4]2− structure is tetrahedral and diamagnetic in nature. |
Statement II: | [NiCl4]2− structure is tetrahedral and diamagnetic in nature. |
Given below are two statements:
Assertion (A): | [NiCl4]2− is paramagnetic while [Ni(CO)4] is diamagnetic though both are tetrahedral. |
Reason (R): | CO is a strong field ligand, thus pairing of electrons takes place in [Ni(CO)4]. |
1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
3. | (A) is True but (R) is False. |
4. | (A) is False but (R) is True. |
I: | [Fe(H2O)6]3+ is strongly paramagnetic whereas [Fe(CN)6]3− is weakly paramagnetic. |
II: | [Fe(H2O)6]3+ has 4 unpaired electrons while [Fe(CN)6]3− has 5 unpaired electrons. |
1. Both I and II are true.
2. I is true and II is false.
3. Both I and II are false.
4. I is false but II is true.
The correct statement among the following is:
1. | [Co(NH3)6]3+ and [Ni(NH3)6]2+, both are inner orbital complexes. |
2. | [Co(NH3)6]3+ and [Ni(NH3)6]2+ both are outer orbital complexes. |
3. | [Co(NH3)6]3+ is an inner orbital complex whereas [Ni(NH3)6]2+ is an outer orbital complex. |
4. | [Co(NH3)6]3+ is an outer orbital complex whereas [Ni(NH3)6]2+ is an inner orbital complex. |
a. | The hexaquamanganese(II) ion contains five unpaired electrons, while the hexacyanomanganese(II) ion contains only one unpaired electron. |
b. | [Mn(H2O)6]2+ is an outer sphere complex, and [Mn(CN)6]4− is an inner sphere complex. |
c. | Arrangement of the electrons in [Mn(CN)6]4− is t2g5eg0. |
