Question

# Identical spheres are undergoing two-dimensional packing in square close packing and hexagonal close packing. Which of the following statements are correct regarding the spheres?

A
The ratio of coordination number for a sphere in first case to that in second case is 2:3.
B
Packing in second case is more effective.
C
Packing in first case is more effective.
D
The stacking of layer on first type packing produces simple cubic structure.

Solution

## The correct options are A Packing in second case is more effective. C The stacking of layer on first type packing produces simple cubic structure. D The ratio of coordination number for a sphere in first case to that in second case is $$2 : 3$$.In square close packing, coordination number $$= 8$$, whereas in hcp, coordination number $$= 12$$. So, the ratio is $$2 : 3$$.Chemistry
