6 : 6 coordination number of NaCl changes to 8 : 8 coordination on:
Open in App
Solution
The correct option is A applying high pressure
Temperature and pressure plays an important role in crystal structure of the compound.
On increasing the temperature, the coordination number of constituents in compound tends to decrease.
On increasing the pressure, the coordination number tends to increase.
The coordination number of 6:6 of NaCl type can be coverted to coordination number of 8:8 of CsCl type by apply high pressure.
Similary, coordination number of 8:8 of CsCl type can be coverted to coordination number of 6:6 of NaCl type by increasing the temperature.
