Question

For tetrahedral coordination, the radius ratio $(r^{+}/r^{-})$ should be

• A. 0.155-0.225
• B. 0.225-0.414
• C. 0.414-0.732
• D. 0.732-1

Answer 1

Answer: (B)

Radius ratio $\left(r^{+}/r^{-}\right)$	Structural arrangement
$0.155-0.225$	Trigonal planar
$0.225-0.414$	Tetrahedral
$0.414-0.732$	Octahedral
$0.732-1.0$	Cubic
