R.C. Mukherjee Test: The Solid State (Old NCERT) - Question 17

The number of octahedral void(s) per atom present in a cubic close-packed structure is   

 [CBSE AIPMT 2012]

Detailed Solution for R.C. Mukherjee Test: The Solid State (Old NCERT) - Question 17

The total number of octahedral void(s) per atom present in a cubic close packed structure is 4. Besides the body centre, there is one octahedral void at the centre of each of the 12 edges. It is surrounded by six atoms, four belonging to the same unit cell (2 on the corners and 2 on face centres) and two belonging to two adjacent unit cells. Since each edge of the cube is shared between four adjacent unit cells, so is the octahedral void located on it. Only 1/4​th of each void belongs to a particular unit cell. Thus, in cubic close packed structure, octahedral void at the body-centre of the cube is 1.
12 octahedral voids located at each edge and shared between four unit cells= 
Total number of octahedral voids =4
We know that in ccp structure, each unit cell has 4 atoms. Thus, the number of octahedral voids is equal to 4/4=1.

R.C. Mukherjee Test: The Solid State (Old NCERT) - Question 29

The structure of MgO is similar to NaCl. The coordination number of Mg is-

Detailed Solution for R.C. Mukherjee Test: The Solid State (Old NCERT) - Question 29

The correct answer is Option C.

For sodium chloride, there are 6 anions around each cation (coordination number of Na=6) because of the 1:1 stoichiometry, there must also be 6 cations around each Cl-  ion.
Similarly, Mg2+O2- also has the octahedral structure and follows NaCl type geometry. 
Therefore, the coordination number of Mg is also 6.
