The NaCl structure can be converted into CsCl structure

A

By applying high pressure

B

By heating to 760K

C

Both by heat and pressure

D

The conversion is not possible

Text Solution

Verified by Experts

The correct Answer is:
A
Since, after applying high pressure , atom in a unit cell, come more closer and hence coordination number increases so NaCl (CN=6) is converted to CsCl (CN=8)
