Question

Correct structure of Penta-1, 3-diene 
a. CH3 - CH = CH - CH = CH2
b. CH3 = CH –CH2- CH = CH2
c. CH3 = C = CH2- CH – CH3
d. CH3 = CH – CH ≡ C – CH3​

Answer 1

Answer:

a. CH3 - CH = CH - CH = CH2

Explanation:

The numbering starts from the double bond as it is more important than the rest of the groups. Penta stands for 5 carbon molecules. Diene states that there are two double bonds present. 1,3 diene means that 2 double bonds are present at the 1st and 3rd positions of the chain.

Answer 2

Answer:

option (a) is the right answer
