In a hypothetical solid C atoms are found to form cubical close packed lattice, A atoms occupy all tetrahedral voids while B atoms occupy all octahedral voids. A and B atoms are of appropriate size, so that there is no distortion in ccp lattice of C atoms. Now if a plane as shown in the following figure is cut, then the cross section of this plane will look like

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
C
From Figure it is clear 4 corners and 2 Face centres lie on the shaded lane. Therefore these will be six .C. atoms, and (Marked A) in T.V donot touch other.
a) not possible, four atom marleed
b) Not possible, atoms .A. in T.V are not shown in figure.
c) Possible since atoms .A. in T.V are not touching each other
d) not possible since atoms .A. in T.V are toucing each other
