Problem 61

Given information

Given molecular formula :

Dipole moment should be equal to zero. 

Step-by-step explanation

Here draw the Lewis structure of the molecule that has zero dipole moment. 

When the dipole moment of the molecule has a symmetrical structure, then only the dipole moment is equal to zero. 

For the zero dipole moment, the bond moments of all the bonds must get canceled out in the structure of the molecule.
