Statement I: Hexagonal closest-packed structure and a cubic closest-packed structure for a given element would be expected to have the same density.
Statement II: The two structures have the same (CN), hence the same packing fraction (density).
Statement II: The two structures have the same (CN), hence the same packing fraction (density).
View answer and explanation
Correct option: A
Both Statement I and Statement II are correct and Statement II is the correct explanation of Statement I
Option A (Both Statement I and Statement II are correct and Statement II is the correct explanation of Statement I) is correct because both HCP and CCP structures have the same coordination number and packing fraction, leading to the same density.
