For each bond, use + and - to show the direction of polarity. Indicate by letter which bond is expected to be the most polar.

(A)  Ge - As

(B)  Ge - Se

(C)  Se - As

The most polar bond is (A,B,C) .

Solutions

Expert Solution

The electronegativity of the three elements are-

Ge = 2.01

As = 2.18

Se = 2.55

Greater the difference in electronegativity, more polar the bond. Also, the partial positive charge is on the element with smaller electronegativity and the negative charge is on the element with higher electronegativity.

a) Ge - As

+ -

b) Ge - Se

+ -

c) Se - As

- +

The most polar bond is B. Ge - Se
