  1. ALKUNA Rumus Umum : Cn H2n-2 Alkuna merupakan senyawa hidrokarbon tak jenuh dengan ikatan rangkap tiga. Contoh : C2H2 : Etuna C3H4 : Propuna C4H6 : Butuna C5H8 : Pentuna

  2. Tata Nama Alkuna: • Rantai utama harus terpanjang dan mengandung ikatan rangkap 3. • Penomoran pada rantai C utama dimulai dari ujung yang terdekat dengan ikatan rangkap 3. • Rantai utama diberi nama sesuai nama alkana tetapi berakhiran una.

  3. Isomer Alkuna Isomer struktur Isomer struktur => Perbedaan pada posisi ikatan rangkap, posisi cabang atau karena perbedaan kerangka atom C Contoh : Senyawa dengan rumus C4H6 1-butuna 2-butuna • C4H6 2 isomer • C5H8 3 isomer

  4. 5-etil-3-metil-1-heptuna 5-Ethyl-3-methyl-hept-1-yne #3: Please note: Alphabetic order of prefixes ignored while selecting parent chain

  5. 6-Isopropyl-7-methyl-oct-3-yne #3: Please note: Alphabetic order of prefixes ignored while selecting parent chain

  6. ISOMER FUNGSIAlkuna dengan Alkadiena CnH2n-2 C4H6
