The dipole moment of cis `C_(2)H_(2)Cl_(2)` isomer is more than that of trans isomer.

Explanation

To understand why the dipole moment of cis-C₂H₂Cl₂ is more than that of the trans isomer, we can follow these steps:

### Step 1: Understand the Structures of the Isomers
- **Cis Isomer**: In the cis isomer of C₂H₂Cl₂, the two chlorine atoms are on the same side of the double bond. The structure can be represented as:
```
Cl
|
H--C==C--H
