Two elements A and B have electronegativities 1 . 2 and 3 . 0 respectively. The nature of bond between A and B would be

Options

  1. Aionic
  2. Bcovalent
  3. Cco-ordinate
  4. Dmetallic

Correct answer

A. ionic

Step-by-step solution

∵ Difference of electronegativity between ( A ) and ( B ) = 3 . 0 - 1 . 2 = 1 . 8 and, a bond having electronegativity difference greater than 1 . 65 is of ionic nature. Hence, bond between ( A ) and ( B ) would be of ionic nature.
