Use the drop-down menus to select the organic

compound model being described.

1. Shows valence electrons:

2. Shows chemical composition but no structure:

3. Is used most for hydrocarbons, shows lines and

functional groups only:

The options are: ball and stick, Lewis structure, molecular, space filling, skeletal, and structural.

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.
