2. Write the structure

  1. 3,3-Dimethylbut-1-yne
  2. 4-Methylpent-2-yne
  3. Hex-1-en-5-yne
  4. Cyclooctyne
  1. HC≡C–C(CH3)3.
  2. CH3–C≡C–CH(CH3)2.
  3. CH2=CH–CH2–CH2–C≡CH: numbering starts from the double bond because both are equidistant from the chain ends.
  4. An eight-membered ring with a triple bond; it is the smallest cycloalkyne that can be isolated.
