Question

Explain dipole moment

Answer 1

Dipole moments occur when there is a separation of charge. They can occur between two ions in an ionic bond or between atoms in a covalent bond; dipole moments arise from differences in electronegativity. The larger the difference in electronegativity, the larger the dipole moment. The distance between the charge separation is also a deciding factor into the size of the dipole moment. The dipole moment is a measure of the polarity of the molecule.

Answer 2

Answer:

lt is the product of charge and distance between two opposite charges.

lt is a vector quantity show the direction is positive to negative.

its symbol is $\Huge \mu$

$\Huge \mu \: = q \times l \: \\ unit \: is \: Debye(D)$

*Non polar molecules has zero dipole due to similar electronegativity value.

* four polar molecule dipole value is not equals to zero . they have defined value of dipole as :-

dipole of $\Huge \: H_2O$ is 1.84 D.

1D = 10^-18e.s.u.cm
