Sagot :
The correct order of increasing dipole moment is BCl3 < BIF2 < BClF2.
What is dipole moment?
- The mathematical product of the separation of the ends of a dipole and the magnitude of the charges.
- More is the electronegativity of an atom more it will have pull of electrons towards itself. For example, in BCl3 electrons will be pulled towards chlorine atom as it is more electronegative than boron.Hence, the dipole moment is cancelled out. So, it will have zero dipole moment.
- In BIF2 and BClF2 , fluorine is more electronegative in nature and it is present in both the molecules.
- But chlorine is more electronegative that iodine atom. So, the dipole moment of BClF2 is more than the dipole moment of BIF2.
