Answer:
Shows valence electrons: Lewis structure
Shows chemical composition but no structure: molecular
. Is used most for hydrocarbons, shows lines and functional groups only:structural
Explanation:
The various formulas for organic compounds required above have been supplied.
The Lewis structure deals with valence shell electron configuration of various atoms. The molecular formula shows the exact chemical composition but not structure of an organic compound. The structural formula connects atoms and functional groups via lines and are easily used to describe alkanes.
An organic compound model that shows valence electrons is called Lewis structure.
Lewis structure can be defined as a type of model that is used for the structural representation of the atom or molecule of a chemical element in an atomic orbital, by using a dot to show the position and distribution of valence electron(s) around the atom or molecule.
This ultimately implies that, a Lewis structure is typically used to show the distribution of electrons that are found in the outermost energy level for the atomic nuclei of a chemical element or compound.
Furthermore, an organic compound model that shows chemical composition but no structure is called molecular.
Lastly, an organic compound model that is mostly used for hydrocarbons to show lines and functional groups only is called skeletal.
