The dipole moment in `BF_(3)` is zero. Explain.

Dipole moment of CO_(2) is zero.

Define dipole moment.

Dipole moment is shown by :

Which of the following molecules have dipole moment ? (i) BeF_(2) " " (ii) BF_(3) " " (iii) NF_(3) " " (iv) H_(2)S

The dipole moment of is 1.5D. The dipole moment of is :

The dipole moments of halo compounds are in the order

An electric dipole is placed in a uniform electric field vecE with its dipole moment vecp parallel to the field . Find (i) the work done in turning the dipole till its dipole moment points in the direction opposite to vecE . (ii) The orientation of the dipole for which the torque acting on it become the maximum.
