Final answer:
When HCl is reacted with 1,3-butadiene at high temperature, the product that will be higher in yield is 1-chloro-2-butene due to thermodynamic considerations and the stability of the resulting carbocation intermediate.
Step-by-step explanation:
When HCl is reacted with 1,3-butadiene at high temperature, the product that will be higher in yield is 1-chloro-2-butene.
In this reaction, HCl adds across the double bond of 1,3-butadiene, resulting in the formation of two possible products: 1-chloro-2-butene and 3-chloro-1-butene. However, due to thermodynamic considerations, 1-chloro-2-butene is favored and will be the major product formed.
This preference for the formation of 1-chloro-2-butene can be explained by the stability of the resulting carbocation intermediate. The positive charge in 1-chloro-2-butene is delocalized over two carbon atoms, which makes it more stable compared to the carbocation intermediate formed in the formation of 3-chloro-1-butene.
