Question

which
of the
following posses net dipole moment?
(a) SO2 (b) BF3 (C) BeCl2 (d) CO2
​

Answer 1

Answer:

d) CO2

Explanation:

Neither because,

S and O2 share electrons for O to complete octet and this makes S have ten electrons. But S can expand its octet.

C and O2 share electrons: C+4e and O2+4e →O^2- + C^4- + O^2- →CO2

H2O→H+ + O^2- + H+

NH3→ 3H+ + N^3-
