Question

Kalau jumlah isomer alkuna dengan rumus molekul C5H10, berapa ?

Answer 1

CH2=CH-CH2-CH2-CH3 (1-pentena)

CH3-CH=CH-CH2-CH3 (2-pentena)

CH2=C-CH2-CH3 (2-metil, 1-butena)
       CH3
 
CH2-CH=C-CH3 (2-metil, 2-butena)
       CH3

       CH3
CH2=C-CH3 (2,2 dimetil, 1-butena)
       CH3

jumlah isomer C5H10 sebanyak 5 buah

Answer 2

CH2=CH-CH2-CH2-CH3 (1-pentena)

CH3-CH=CH-CH2-CH3 (2-pentena)

CH2=C-CH2-CH3 (2-metil,1-butena)
       CH3
 
CH2-CH=C-CH3 (2-metil,2-butena)
       CH3

       CH3
CH2=C-CH3 (2,2 dimetil,1-butena)
       CH3
Kalo isomer C₅H₁₀ ya ada 5.
