Draw the molecular dipole or demonstrate the symmetrical cancellation of vectors in the following molecule, and describe it as polar or nonpolar.

             NCl3

**Understanding Molecular Polarity**

Here is a detailed explanation of several molecular structures and their associated polarity:

1. **A. Structure (Polar)**
   - Diagram: A molecule with a central nitrogen atom connected to two chlorine atoms and another chloride ion. There is a pair of non-bonding electrons on the nitrogen. The dipole moment arrows point away from the nitrogen towards the chlorines, forming an overall net dipole moment in one particular direction, indicated by a red arrow.
   
2. **B. Structure (Polar)**
   - Diagram: A central nitrogen atom bonded symmetrically to two carbon atoms, which are further bonded to chlorine atoms. Blue dipole arrows show an unequal distribution of charge, suggesting a net dipole moment in one direction, highlighted by the red arrow.
   
3. **C. Structure (Polar)**
   - Diagram: Nitrogen is in the center, bonded to one carbon and one chloride, and the carbon is bonded to another chloride. This creates an asymmetrical shape with a lone pair on the nitrogen, generating a significant net dipole moment indicated by the blue arrows and the red arrow.

4. **D. Structure (Nonpolar)**
   - Diagram: A trigonal planar arrangement with nitrogen central and bonded to three chlorine atoms. There are no lone pairs, and the dipole moments cancel each other, resulting in no net polarity.

5. **E. Structure (Polar)**
   - Diagram: This structure features nitrogen bonded in a way that appears symmetrical but with lone pairs disrupting symmetry. Blue arrows represent dipole moments; the overall molecule has a net dipole as indicated by the red arrow.

6. **F. Structure (Nonpolar)**
   - Diagram: Three symmetric bonds around a nitrogen with lone pairs. Although there are dipole moments, they cancel out due to symmetry, rendering the molecule nonpolar.

7. **G. Structure (Nonpolar)**
   - Diagram: Nitrogen is centrally located with three chlorine atoms positioned symmetrically around it. The symmetry ensures dipole cancellations, and no net direction is formed.

8. **H. Structure (Nonpolar)**
   - Diagram: A structure resembling a tetrahedral arrangement with nitrogen in the center, surrounded by chlorines equally spaced. Full symmetry leads to the cancellation of dipole moments, resulting in a nonpolar molecule.

**Explanation of Polarity:**
Polarity in molecules arises due to unequal sharing of electrons between atoms with
