Select the corrent statement `(s)`
(a) The `C.N.` of cation occupying a tetrahedral hole is `4`
(b) The `C.N.` of cation occupying an octabedral hole is `6`
(c ) In schottky defects, density of the lattice decreases

A

a,b

B

b,c

C

a,b,c

D

a,c

Text Solution

Verified by Experts

The correct Answer is:
C
Since terthadral holes are surrounded by a nearest neighours so, the `C.N` of cation occupying tetrahedral hole is `4` since octahedral holes is surrounded by six nearest neighource so, `C.N` of cation accopying outahedral is `6` In schotily defecty defects a parts of anion and cation so density of lattice decreases

In a hypothetical solid C atoms form C C P lattice with A atoms occupying all the Tetrahedral Voids and B atoms occupying all the octahedral voids A and B atoms are of the appropriate size such that there is no distortions in the CCP lattice. Now if a plane is cut ( as shown ) then the section would like

In a structure, A atoms have fcc arrangement B atoms occupy all the tetrahedral sites and C atoms occupy half the octahedral sites. The formula of the compound is

Assertion: In a crystal, the size of the cation is larger in a tetrahedral hole than in an octahedral hole. Reason: Cations occupy more space than atoms in crystal packing
