Which statement (s) is/are correct about dipole moment (I) Debye is equivalent to 3.33 xx 10^(-30) Cm (II) 1 Debye is equivalent to 10^(-18) esu cm (III) SI unit of dipole moment is coulomb meter (Cm) (1 Cm = q xx d = 1.602 xx 10^(-19) xx 10^(-9) m) (IV) Dipole moment of a molecule is useful to explain the shape of a molecule and also to predict other properties of the molecule .

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 moments 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 distinguish between cis- and trans- isomers, ortho, meta and pare-forms of a substance, etc. Q. Which is a polar molecule?
