Vitamin C Lewis Structure
Question:
Draw the Lewis structure for ascorbic acid (vitamin C).
Lewis Structure:
Two atoms from different elements can come together and form some number of covalent bonds, in which they share some number of valence electron pairs. This is the simplest example of a covalent chemical bond. An example is hydrochloric acid (HCl), in which hydrogen and chlorine atoms form a single covalent bond. There are numerous larger covalent compounds with several atoms originating from different elements. We can describe the arrangement of all their bonding and non-bonding valence electron pairs through a Lewis structure. Each atom in the structure will have a certain preferred total number of covalent bonds formed.
Answer and Explanation: 1
Vitamin C is both a covalent compound and an organic compound. It is composed of carbon, hydrogen and oxygen atoms.There is a ring unit of 4 carbon atoms and 1 oxygen atom. Attached to this ring are several substituents. Based on organic chemistry, a molecule of vitamin C contains alcohol, alkene and ester functional groups. The Lewis structure is shown below. Each carbon atom maintains a total of 4 covalent bonds. Each hydrogen atom has 1 covalent bond. Each oxygen atom has 2 covalent bonds. Each oxygen atom also has 2 pairs of non-bonding valence electrons, which are omitted in the Lewis structure shown below:
