. The molecule which has zero dipole moment is

Best Answer

Explanation:-

•  Dipole moment is a vector quantity and the net dipole moment of a molecule is given by the vector law of addition 
• CH₂CL₂  The carbon atom is sp³ hybridized; the dipole moment by the two C-Cl bonds is not canceled out by the

resultant dipole moment of two hydrogen bonds for this molecule causes net dipole moment .

• BF₃ The Boron atom sp₂ hybridized and  the molecule has trigonal planar structure So the dipole moment of three

B-F bonds cancel out each other and the molecule has net zero dipole moment .

•  NF₃ The molecules have trigonal pyramidal structure  and  due to structure the  individual dipole moment of bonds 

are not able to cancel out each other and hence molecule possess  net dipole moment.

• ClO₂ Molecule have bent structure and due to structure the  individual dipole moment of bonds  are not able to

cancel out each other and hence molecule possess  net dipole moment.

Final Answer :-

(B) BF₃ have zero dipole moment
