Which of the following statement is not correct?

Options

  1. APacking efficiency of hcp and ccp lattices are identical
  2. BPacking efficiency of fcc lattice > Packing efficiency of ccp lattice
  3. CPacking efficiency of fcc lattice = Packing efficiency of ccp lattice
  4. DPacking efficiency of hcp lattice = Packing efficiency of fcc lattice

Correct answer

B. Packing efficiency of fcc lattice > Packing efficiency of ccp lattice

Step-by-step solution

Face centred cubic packing (fcc) and cubic close packing (cсp) has same packing efficiency.
