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

          H2O   

### Molecular Polarity and Structure

Each diagram represents a different molecule structure with resultant molecular polarities identified.

#### Diagram Analysis:

1. **A. Polar**
   - The diagram shows a molecule with a trigonal pyramidal shape. Three hydrogen atoms are bonded to a central atom with lone pairs of electrons.
   - Blue arrows (indicating dipole moments) point outwards from each bond.
   - The red line forms a triangular shape connecting each hydrogen, indicating an asymmetrical distribution.

2. **B. Polar**
   - The structure resembles a bent molecule, with two hydrogen atoms bonded to a central atom.
   - Lone pairs are present, and blue arrows indicate the dipole direction.
   - The asymmetry in electron distribution is shown by the red boundary.

3. **C. Nonpolar**
   - Here, a linear shape is depicted with symmetrical distribution.
   - Two hydrogen atoms are connected to the central atom with equal blue dipole arrows in opposite directions, canceling each other out.

4. **D. Nonpolar**
   - This structure is again linear with two hydrogen atoms bonded.
   - Blue arrows point away from the central atom equally, indicating symmetry and no net dipole.

5. **E. Polar**
   - A bent structure similar to B is shown, emphasizing the presence of lone pairs with blue arrows representing dipoles.
   - The red line highlights the asymmetric shape, leading to polarity.

6. **F. Nonpolar**
   - A tetrahedral structure where negative charges are placed symmetrically around the central atom.
   - Blue dipole arrows point outwards and cancel each other due to symmetry.

7. **G. Polar**
   - This is a tetrahedral shape but unlike F, there is asymmetrical electron distribution due to lone pairs.
   - The red arrow and structure illustrate the net dipole moment.

8. **H. Nonpolar**
   - Linear configuration with symmetry in charge distribution.
   - Blue arrows in opposite directions indicate no net dipole.

Diagrams are simplified to demonstrate electron distribution and molecular shape affecting polarity. Polar molecules have a net dipole moment due to asymmetry, while nonpolar ones have symmetrical electron distribution, canceling out dipole moments.
