Calculate the percentage of covalent character of HX having bond length = 1.62 Å and observed dipole moment = 0.39 D.

Text Solution

Verified by Experts

Calculated `mu = 4.8 xx 10^(-10)` esu `xx 1.62 xx 10^(-8) cm = 7.776` D
Percentage ionic character = `(0.39)/(7.776) xx 100 = 5%`
Percentage covalent character = `100-5 = 95` %

Polar covalent molecules exhibit dipole moment. Dipole moment is equal to the product of charge separation, q and the bond length d for the bond. Unit of dipole moment is Debye. One Debye is equal to 10^(-18) esu-cm. Dipole moment is a vector quantity. It has both magnitude and direction. Hence, dipole moment of a molecule depends upon the relative orientation of the bond dipoles, but not on the polarity of bonds alone. A symmetrical structure shows zero dipole moment. Thus, dipole moment helps to predict the geometry of a molecules. Dipole moment values can be used to disinguisd between cis- and trans- isomers, ortho-, meta - and para - forms of a substance, etc. The dipole moment value of H-X molecule is 1.2 Debye.
