The total number of aldehydes structural having the molecular formula C5H10O is -

To find the total number of aldehydes with the molecular formula C5H10O, we can follow these steps:

Step 1: Determine the number of carbon atoms in the formula. In this case, the molecular formula C5H10O indicates that there are 5 carbon atoms.

Step 2: Determine the number of hydrogen atoms in the formula. The molecular formula C5H10O indicates that there are 10 hydrogen atoms.

Step 3: Determine the number of oxygen atoms in the formula. The molecular formula C5H10O indicates that there is 1 oxygen atom.

Step 4: Calculate the number of possible aldehydes. To form an aldehyde, one of the carbon atoms in the molecule must have a double bond with an oxygen atom and a single bond with a hydrogen atom. This carbon atom is called the carbonyl carbon.

In a molecule with 5 carbon atoms, there are 5 possible positions for the carbonyl carbon. Therefore, there are 5 possible aldehydes with the molecular formula C5H10O.

So, the total number of aldehydes with the molecular formula C5H10O is 5.
