What is the structure of hex-1-yn-4-one?
I think this is the correct structure. (::: Indicates a triple
bond) O HC:::C-CH2-C-CH2-CH3 This didn't post as I thought it
would. But there is a triple bond on the first C atom and the O is
bonded to the fourth C atom. It should be: HC-C-CH2-CO-CH2-CH3
with a triple bond between the 1st and 2nd carbon, and a double
bond between the 4th carbon and the oxygen.
