Question

Dipole moment of Bef2 is zero why

Answer 1

deployment of them BF 280 Bhatija water unit 80 and element are very high compression of the iron and phosphorus chloride magnesium sector.

Answer 2

_____Answer____

Dipole moment:-

✒ Dipole moment is the product of the magnitude of the charge and the distance between the centres of positive (+) and negative (-) charge.

✒The polarity of Covalent bond results in the form of electric dipole passing a permanent dipole moment which is defined as :

=> Dipole Moment (u)= charge (Q)×distance of separation (r)

=> It is expressed in Or it's C.G.S unit :- Debye (D)

S.I unit:- C-M

=> It is vector Quantity and is pointing towards (-ve) end.

=> The dipole moment of BeF2 is zero :-

The dipole moment of BeF2 is zero because it is linear in shape .It is a linear molecule. In BeF2 F is more electronegative than Be so due to equal and opposite vectors It's resultant dipole moment is zero.
