The experimental value of the dipole moment ofHClis1.03  D. The length of theH-Clbond is1.275 . The percentage of ionic character inHClis:
[Given:1D=10-18esu cm]

Options:

Answer:
C
Solution:

% Ionic character=Experimental value of dipole momentTheoritical value of dipolemoment×100

=μexpμtheo×100

Where:

μexp =1.030andμtheo=q×d

d=1.275=1.275×10-8cm

q=4.8×10-10 esu

μtheo=4.8×10-10×1.275×10-8esu-cm

=4.8×1.275×10-18esu-cm

=4.8×1.275D

1D=10-18esu cm

% Ionic character=1.034.8×1.275×100=17
