Question

represent diagrammatically the bond moment and the resultant dipole moment in CO2 NF3 and CHCI3​

Answer 1

Answer:

)

Applicationsofdipolemoment:

Dipole moment (μ) = charge (Q) * distance of separation (r)

Dipole moment is usually expressed in Debye units (D).

(a) It helps to predict polar and non-polar nature of compounds

(b) The percentage of ionic character can be calculated:

% of ionic character =

μcalculated

μobserved

∗100

(c) It helps to know the symmetry of molecule. Symmetrical molecules have zero dipole moment, although they have two or more polar bonds.

For example,

The dipole moment in case of BeF

2

is zero. This is because the two equal bond dipoles point in opposite directions and cancel the effect of each other.

(ii) The diagrams and net dipole moments are shown in the figures above:
