Answer:
trans-1,3-pentadiene is more stable than 1,4-pentadiene due to presence of a conjugated double bond.
Explanation:
Here,
H(hydrogenated pdt.) is same for both 1,4-pentadiene and 1,3-pentadiene as they both produce pentane after hydrogenation
H(diene) depends on stability of diene.
More stable a diene, lesser will be it's H(diene) value (more neagtive).
trans-1,3-pentadiene is more stable than 1,4-pentadiene due to presence of a conjugated double bond.
Hence, is higher (less negative) for trans-1,3-pentadiene
Explanation: This is a reaction of oxidation of in the presence of acidified
. Acidified
is a strong oxidizing agent.
To balance out the on the reactant side, we write
on the product side.
Balancing out the following reaction gives us:
