A metal adopts two allotropic forms with the following types of arrangements
In the allotrope 'A' what is the maximum inter atomic distance in its unit cell, if the minimum inter atomic distance in the unit cell is d'?

A

`sqrt6d`

B

`sqrt3d`

C

`6sqrtd`

D

`2sqrt3d`

Text Solution

Verified by Experts

The correct Answer is:
B
Maximum inter atomic distance covered by there spheres i.e. body diagonal `=sqrt3a`
Minimum interatomic distance `=d=sqrt3d.`

Allotropy is the occurence of same element in two or more different physical forms having more or less similar chemical properties but different physical properties. The different forms of the element are called allotropes. Allotropy is due to the difference in the arrangement of atoms in solid state. Allotropes may be crystalline or amorphous In which of the following all the atoms are not sp^(3) hybridization
