In crystalline solids, atoms or molecules are arranged in a regular and long range order fashion in a three dimensional pattern. Q. The fraction of `Ni^(2+) and Ni^(3+)` ions in `Ni_(0.98)O_(1.00)` is:

A

96, 4

B

90, 10

C

4, 96

D

10, 90

Text Solution

Verified by Experts

The correct Answer is:
A
Let `Ni^(2+)` be a and `Ni^(3+)` be (100-a), then `axx2+(1-a)xx3=(2xx1.0)/(0.98)therefore=95.9%`.

If in the mixed carbonyl, the other ligand is also pi acceptor, it would complete with the ligand CO for gaining the metal d_pi electron charge. The higher is the extent of back donationin CO, the lesser will be the stretching vibration frequency for C - O bond. If PPh_3 is better pi - acceptor than CO , then answer the following. Select correct order of stretching vibration frequency C - O bond in following molecules I. [Ni(CO)_4] II. [Ni(PF_3)(CO_3)]
