A molecular model of uric acid is shown in the illustration below. Draw the complete electron-dot structure of uric acid including the lone pairs and multiple bonds, Provide the hybridization of each carbon atom. (gray = C, white = H, red = O, and blue = N)

• A. Each of the carbon atoms are sp³ hybridized.
• B. Each of the carbon atoms with a double bond is sp² hybridized and each of the carbon atoms with a single bond are sp³ hybridized.
• C. Each of the carbon atoms are sp² hybridized.
• D. Each of the carbon atoms with a double bond is sp³ hybridized and each of the carbon atoms with a single bond are sp² hybridized.

Answer: (C)
