The formula for fructose is C6H12O6. Option 1 (C12H22O11) is the formula for sucrose, not fructose. Sucrose is a disaccharide consisting of glucose and fructose. Option 3 (C12H19C1308) and Option 4 (C6H10O8) are not the correct formulas for fructose.
Fructose is a monosaccharide, also known as a simple sugar. It is commonly found in fruits and honey, and it is the sweetest of all natural sugars. The correct formula, C6H12O6, indicates that it contains 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms. This formula represents one molecule of fructose.
It is important to note that the formula for fructose may sometimes be written as C6H12O6•H2O to indicate that it can exist in a hydrated form. However, in the context of the given options, the formula C6H12O6 is the accurate one.
