The dipole moment of `BF_3` is zero eventhough the B-F bonds are polar, Justify.

The net dipole moment of a polyatomic molecule depends on the spatial arrangement of various bonds in the molecule. The dipole moment of BF_3 is zero while that of NF_3 is not zero. Justify

Explain why BeH_2 molecule has zero diple moment even though the Be-H bond are polar.

In the following question, an Assertion (A) is followed by a corresponding Reason (R). Use the following keys to choose the appropriate answer. Assertion : The dipole moment in case of BeF_2 is zero. Reason : The two equal bond dipoles point in opposite directions and cancel the effect of each other.

The dipole moment of CH_3X (where X is a halogen) follows the order

Define dipole moment. The dipole moment of BF_3 is zero. Why?

Assertion : Dipole moment of CH_(3)F is greater than CH_(3)Cl Reason : C-Cl bond is more polar than C-F bond.

The formation of chemical compounds takes place as a result of combination of atoms of various elements. The dipole moment of NH_3 is 0.49 D and that of BF_3 is zero. From the above values predict molecular structure of NH_3 and BF_3 .
