1.	The correct naming of the compound CH≡C-CH=CH-CH3 is __________(a) Pent-3-en-1-yne(b) Pent-2-en-4-yne(c) Pent-3-ene-1-yne(d) Pent-2-ene-4-yneI have been asked this question during a job interview.This interesting question is from Haloalkanes Nomenclature topic in division Haloalkanes and Haloarenes of Chemistry – Class 12
Answer» Correct option is (a) Pent-3-en-1-yne Easiest explanation: The lower SET of LOCANTS is 1, 3 rather than 2, 4. This compound is named as a derivative of alkyne and not alkenes. Also, the TERMINAL ‘e’ in ene is dropped because it comes before ‘y’ of yne.
