Which of the following has maximum dipole moment?

Options

A. `NCl_(3)`
B. `NBr_(3)`
C. `NH_(3)`
D. `NI_(3)`

Explanation

To determine which of the given nitrogen compounds has the maximum dipole moment, we will analyze each compound based on the electronegativity differences between nitrogen and the other atoms it is bonded to. The compounds to consider are NCl3, NBr3, NH3, and NI3.

### Step-by-Step Solution:

1. **Identify the Compounds**: The compounds we are analyzing are NCl3 (Nitrogen trichloride), NBr3 (Nitrogen tribromide), NH3 (Ammonia), and NI3 (Nitrogen triiodide).

2. **Understand the Structure**: All these compounds have a pyramidal shape due to the presence of a lone pair on nitrogen. This shape will influence the dipole moment.
