Answer 2

Molecular Formula of Water

The molecular formula of water is H2O. This means that a water molecule consists of two hydrogen atoms bonded to one oxygen atom.

Electron Dot Formula of Water

The electron dot formula, also known as Lewis dot structure, represents the arrangement of valence electrons in a molecule. In the case of water, the electron dot formula is as follows:

H: .   . :H
     .
O: .
     .
H: .   . :H

In this representation, the dots represent the valence electrons of the atoms. Each hydrogen atom shares one electron with the oxygen atom, forming a covalent bond. The oxygen atom shares two electrons with each hydrogen atom, resulting in a total of four shared electrons (two from each hydrogen) and two lone pairs of electrons on the oxygen atom.

Structural Formula of Water

The structural formula of water provides information about the arrangement of atoms and the bonds between them. The structural formula of water is as follows:

    H
     |
H - O - H
     |
    H

In this representation, the lines represent the bonds between the atoms. Each line represents a single covalent bond. The oxygen atom is in the center, with two hydrogen atoms bonded to it. The structural formula shows the spatial arrangement of the atoms in the water molecule.

It's important to note that the structural formula is a two-dimensional representation of a three-dimensional molecule. In reality, the water molecule has a bent or V-shaped geometry due to the repulsion between the lone pairs of electrons on the oxygen atom
