Hence, the net dipole moment of NF3 is less than that of NH3. In NH3, Nitrogen is more electronegative than H, so it will attract the shared pair of electrons towards itself.As a result dipole due to Nitrogen is in same direction as the resultant dipole moment due to N-H bond& hence the net dipole increases. BClF2 and BIF2 are polar since their structures are not symmetric. since in BCl3, three Cl groups are identical, BCl3 has a symmetric structure. BClF2 Question Place the following in order of increasing dipole moment. BClF2 Place the following in order of increasing dipole moment. Due to their different three-dimensional structures, some molecules with polar bonds have a net dipole. 1 Approved Answer Mark B answered on Novem3 Ratings ( 15 Votes) the electronegativity sequence: F > Cl > I all BCl3, BClF2, and BIF2 are trigonal planar molecules. ScienceChemistryPlace the following in order of increasing dipole moment.

As a result dipole due to all F is in opposite direction to the resultant dipole due to N-F bonds,therefore the net dipole decreases. Individual bond dipole moments are indicated in red. Since in case of NF3, fluorine is more electronegative than nitrogen, so it will attract the shared pair of electron towards itself from nitrogen. The dipole moment of bcl3 is smaller than that of other molecules, such as water, because the charges are more evenly distributed within the bcl3 molecule. This can be explained on the basis of the directions of the dipole moments of each individual bond in NF3 and NH3. The dipole moment of a molecule is a measure of the separation of positive and negative charges within the molecule.

However, the net dipole moment of NH3 (1.46 D) is greater than that of NF3 (0.24 D). The short answer to your question is that Yes, BrF3, Bromine trifluoride, has a molecular dipole moment of 1.19 D, where D stands for Debye. Since fluorine is more electronegative than hydrogen, it is expected that the net dipole moment of NF3 is greater than NH3. Hence, both molecules have a pyramidal shape.

The opposite direction of the dipole moment in the molecule cancels each other. The dipole moment is directed towards the more electronegative atom in the compound. In both molecules i.e., NH3 and NF3, the central atom (N) has a lone pair electron and there are three bond pairs. Answer Verified 296.1k + views Hint: The dipole moment is the product of negative or positive charge and the distance between the centers of positive and negative charges.
