Question

Give the IUPAC name of
CH3-CH=CH-CH2-CHO

Answer 1

The IUPAC name of  CH3-CH=CH-CH2-CHO is pent-3-enal or pent-3-en-1-al.

The given compound is CH3-CH=CH-CH2-CHO.

1) We see that the parent chain contains 5 carbon atoms. So, the name must contain "pent" in it.

2) The priority of aldehyde is more than double bonds. So, the carbon naming would start from the right most end in it.

3) 3-ene must be there in the name because the double bond is shared by the 3rd and 4th carbon atoms.

4) The name ends with -al because aldehyde is present in the first carbon atom.

Thus, the IUPAC name stands as pent-3-enal or pent-3-en-1-al.
