The isomeric alkynes of given molecular formula along with their IUPAC names and circle the acetylenic hydrogen of each terminal alkynes. Interpretation: The isomeric alkynes of given molecular formula are to be drawn along with their IUPAC names and the acetylenic hydrogen of each terminal alkynes is to be circled. Concept introduction: A molecular formula and structural isomer is related to each other. A molecular formula describes the total number of atoms and their symbol in a molecule, whereas structural isomers possess the same molecular formula but atoms are arranged in a different manner. International Union of Pure and Applied Chemistry gave guidelines to write the chemical name of molecules. In case of pure alkynes without any functional group , numbering starts from the side that is near to the triple bond and alkyne molecules end with –yne. Acetylenic hydrogen is acidic as compared to rest of hydrogen atoms that are present in alkyne. The acetylenic hydrogen dissociates easily due to acidic nature.
