A molecule like H-X is 50% ionic if electronegativity difference of H and X is x eV. The value of 10x is_____________.

Open in App

Solution

A molecule like H-X is 50% ionic if electronegativity difference of H and X is 1.9 eV.
But it is equal to x eV.
$x e V = 1.9 e V$
Hence, $10 x e V = 10 \times 1.9 e V = 19 e V$
Hence, the value of 10x is $19 e V$ .

are electronegativities of B and A, respectively and

X_{B} > X_{A} .

X_{A} = 1.84 X_{B} = 3.48,
