Write Lewis structures for the following molecules:
(a) Formic acid, $\mathrm{HCOOH}$, in which the ECP plot is:
(b) Acetonitrile, $\mathrm{CH}_{3} \mathrm{CN} ;$
(c) Vinyl chloride, $\mathrm{CH}_{2} \mathrm{CHCl}$, the molecule from which PVC plastics are made.

Key Concepts

Lewis Structures

Lewis structures are diagrams that show the bonding between atoms of a molecule and the lone pairs of electrons that may exist. They use lines to represent bonds and dots to indicate valence electrons, providing a visual representation of how atoms in a molecule share or transfer electrons to form chemical bonds.

Valence Electrons

Valence electrons are the outermost electrons of an atom and play a crucial role in chemical bonding. When constructing Lewis structures, the total number of valence electrons available for bonding and lone pairs is summed up for all atoms in the molecule, ensuring that electron count is conserved throughout the structure.

Octet Rule

The octet rule is a chemical rule of thumb that states atoms tend to form bonds in such a way that each atom ends up with eight electrons in its valence shell, similar to the electron configuration of a noble gas. This rule is used as a guideline when arranging electrons in Lewis structures, although there are exceptions for elements in other periods or with unusual bonding.

Formal Charge

Formal charge is a bookkeeping tool used to assign charge values to atoms within a Lewis structure based on the assumption of equal sharing of electrons in bonds. It helps determine the most stable electron arrangement by assigning minimal charges and identifying the most likely structure among potential resonance forms.

Multiple Bonds

Multiple bonds, such as double or triple bonds, occur when two or more pairs of electrons are shared between atoms. Recognizing and drawing multiple bonds in a Lewis structure is essential for satisfying the octet rule in molecules where single bonds do not provide enough electrons to fill the valence shells of the atoms involved.
