Verified step by step guidance1
Identify the structure of a fatty acid with 18 carbons. A fatty acid with 18 carbons and no double bonds is known as a saturated fatty acid.
The general formula for a saturated fatty acid is CnH2nO2. For an 18-carbon fatty acid, the formula is C18H36O2.
The condensed structural formula for an 18-carbon saturated fatty acid is CH3(CH2)16COOH.
The common name for the 18-carbon saturated fatty acid is stearic acid.
Review the images provided: The first and fourth images depict the structure of stearic acid, confirming the condensed structural formula as CH3(CH2)16COOH.
