Q. If the electronegativity difference between two atoms $A$ and $B$ is $2.0$, then the percentage of covalent character in the molecule is

AMUAMU 2008

Solution:

According to Hannay and Smith equation
$\therefore \%$ ionic character
$=16\left(x_{A}-x_{B}\right)+3.5\left(x_{A}-x_{B}\right)^{2}$
where, $x_{A}$ and $x_{B}$ are the electronegativites of the atoms $A$ and $B$ respectively.
$\therefore \%$ ionic character $=16(2)+3.5(2)^{2}$
$ = 32 + 14 = 46\%$
