Identify the correct statement(s)
A. CsCl changes to NaCl structure on heating
B. NaCl changes to CsCl structure on applying pressure
C. Coordination number increases on applying pressure
D. Coordination number increase on heating.
A. CsCl changes to NaCl structure on heating
B. NaCl changes to CsCl structure on applying pressure
C. Coordination number increases on applying pressure
D. Coordination number increase on heating.
Correct Answer – A::B::D
(a) is correct when heating is done, the coordination number decreases and CsCl changes to NaCl structure because on applying pressure coordination number increases.
(c) Is wrong because coordination number increases on applying pressure .
(d) is wrong becasue coordination number decreases on heating.
