The limiting radius ratio for tetrahedral shape is:
(a) 0 to 0.155
(b) 0.225 to 0.414
(c) 0.155 to 0.225
(d) 0.414 to 0.732
Answers
The answer is b it's 0.225 to 0.414
Answer:
Concept :
The limiting radius ratio (=r+/r-) is the smallest value for the ionic radii ratio (=r+/r-) that this structure can have while being stable. The radius of the cation is r+, and the radius of the surrounding anions is r-. It's worth noting that anions are often larger than cations.
Given :
The tetrahedral shape's limiting radius ratio is:
(a) 0 to 0.155
(b) 0.225 to 0.414
(c) 0.155 to 0.225
(d) 0.414 to 0.732
Find :
To find the correct option
Answer :
Correct option C is correct.
When there are four bonds and no lone pairs around the core atom in a molecule, it is called a tetrahedral structure. The atoms that are bound to the core atom are arranged in a tetrahedron with 109.5 angles between them. Sp3 hybridization is most common in molecules with tetrahedral geometries. The molecule's form is as follows:
The radius ratio is defined as the ratio of the cation to the ratio of the anion.
It is the ratio of the radius (r) of the atom or ion that can fit perfectly in the octahedral vacuum formed by spheres of radius R. The radius ratio for trigonal voids is 0.155, for tetrahedral voids is 0.225, for octahedral voids is 0.414, and for cubic voids is 0.732.
As a result, the tetrahedral structure's limiting radius ratio is 0.225-0.414.
