WebIn polyatomic molecules, each bond has an individual bond moment. The dipole moment (μ) of a molecule is the vectorial addition of such bond moments. In the cases where all the individual bond moments are zero (homoatomic molecules), the resultant dipole moment is always zero. However, the converse is not true.

WebThe molecules of the two liquids interact with one another when they are put into two open containers. Hexane and ethanol are two distinct compounds, and because of the differences in their structural makeup, they also have different characteristics and different attractive forces. Hexane molecules lack any dipole moment and are non-polar.

WebPolyatomic molecules have more than one vibrational frequency. The number can be calculated from the following. One atom in the molecule can move independently in three directions, the x, y, and z directions in a Cartesian coordinate system. Therefore, in a molecule with n atoms, the n atoms have 3 n independent ways they can move. WebThe presence of polar bonds in a polyatomic molecule suggests that the molecule has non-zero dipole moment. ... Verified by Toppr. Correct option is . A. 0. All molecules with polar bonds do not have dipole moment. Sometimes due to regular shape, dipole moment vectors cancel out each other and the molecule becomes non-polar.

WebAn analysis of molecular dipole moments in polyatomic molecules requires us to apply our understanding of molecular geometry.
