In HCP of A, 1 3 of tetrahedral voids are occupied by B . What is the formula of the compound?

Options

  1. AA₂ B₃
  2. BA₃ B₂
  3. CA B₃
  4. DA₂ B

Correct answer

B. A₃ B₂

Step-by-step solution

No. of atoms (A)=6(h c p) , no. of B atoms = 1 3 12=4 Hence, the formula of the compound is A₆ B₄ or A₃ B₂ .
