Assertion:A tetrahedral void is surround...

Assertion:A tetrahedral void is surrounded by four spheres and an octahedral void is surrounded by six spheres.
Reason:The number of tetrahedral voids is double the number of close packed spheres and number of octahedral voids is equal to number of close packed spheres.

A

If both assertion and reason are true and reason is the correct explanation of assertion

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false

D

If both assertion and reason are false

Text Solution

Verified by Experts

The correct Answer is:
B
Tetrahedral voids are called so because a tetrahedron is formed when the centres of the four spheres are joined , while octahedral voids form octahedron when centres of surrounding six spheres are joined
