The pair from the following pairs having both compounds with net non-zero dipole moment is
Options
- A1 ,   4 -Dichlorobenzene, 1 ,   3 -Dichlorobenzene
- Bcis-butene, trans-butene
- CCH 2 Cl 2 ,   CHCl 3
- DBenzene, anisidine
Correct answer
C. CH 2 Cl 2 ,   CHCl 3
Step-by-step solution
The dipole moment is the vector sum of all the bond moments. The CH 2 Cl 2 and CHCl 3 both have net non-zero dipole moment because the bond moments are not cancelled each other due to their tetrahedral structure. The 1 ,   4 -dichlorobenzene, trans-butene, benzene have zero dipole moment due to cancellation of bond moments. The 1 ,   3 -dichlorobenzene, cis-butene, anisidine has non-zero dipole moment.
