The term bio-diesel does not refer to a specific compound, but covers a class of compounds. The popular form of bio-diesel contains a methyl ester; however, there are also ethyl and propyl ester forms( and larger). List two advantages, two disadvantages, or one of each for having bio-diesel in the methy, ethyl, or propyl form (basically two examples that compare/contrast the size of bio-diesel). In addition, draw the major compound (exact structure no R groups) formed when synthesizing bio-diesel using anhydrous ethanol, potassium hydroxide and coconut oil.
