In a solid, atom M occupies ccp lattice and 1 / 3^ rd of tetrahedral voids are occupied by atom N . Find the formula of solid formed by M and N .

Options

  1. AM₃ N₂
  2. BM₂ N₃
  3. CM₄ N₃
  4. DM₃ N₄

Correct answer

A. M₃ N₂

Step-by-step solution

Suppose number of M atoms =n Then number of tetrahedral sites =2 n Number of N atoms = 1 3 (2 n) Ratio M: N=n: 2 3 n=3: 2 , i.e., formula is M₃ N₂
