In a compound AB, electro negativity difference between A and B is 1.9 . Atomic radius A and B are 4 A ° and 2 A ° . The distance between A and B atoms means d A − B is

Options

  1. A6.72 A °
  2. B5.82 A °
  3. C6.9 A °
  4. D7.5 A °

Correct answer

B. 5.82 A °

Step-by-step solution

d A − B = r A + r B − 0.09 ( x A − x B ) = 6 − 0.09 ( 1.9 ) ≈ 5.829
