And the name is Hexadecane. Where decane means ten, hexa means six. Six plus ten gives us 16. And the way that we basically go from this name to the name of this particular fatty acid is by removing the E at the end of the hydrocarbon name and replacing it with OIC and then adding acid afterwards. So in this particular case, we have hexadechanoic. Acid is the proper systematic name for the more common name of palmitic acid.
