1 , 4 dicholorobenzene has dipole moment----------

Why BCl_3 molecule has zero dipole moment.

Define point dipole.

(Attempt any nine of the following questions) There is an electric dipole on the x-y plane. Its dipole moment is 4 x 10^(-9) Cm . On . the same plane there is also a uniform electric field of magnitude 5x10^4 NC^(-1) . If the axis of the dipole makes an angle 30° with the electric field, calculate the magnitude of the torque acting on the dipole and also mention the di rection of torque.

What is centre of the dipole?

What is the direction of magnetic dipole moment?

Which one of the following has the highest dipole moment and why: CH_2Cl_2 , CHCl_3 , C Cl_4

An electric dipole is formed by + 4muC and - 4muC charges at 5 mm distance. Calculate the dipole moment.

The earth's magnetic field at the equator is approximately 0.4G. Estimate the earth's dipole moment.
