(a)
To determine: The rank of each compound in order of increasing heat of hydrogenation.
Interpretation: The rank of each compound in order of increasing heat of hydrogenation is to be shown.
Concept introduction: Heat of hydrogenation aids in find out the stability of double bonded compounds. The addition of hydrogen atom in an unsaturated compound known as hydrogenation and the amount of energy released during the process of hydrogenation known as heat of hydrogenation. Heat of hydrogenation is always shown by negative sign; if the value of heat of hydrogenation is small then double bonded compounds possess more stability and vice-versa.

For example, 1 = fastest or most reactive dienophile, 4 = slowest or least reactive dienophile.arrow_forwardo chem - please show stereochemistry and break down each step as much as possiblearrow_forward
- Rank the following dienes in their rate of reaction with the same dienophile in a Diels-Alder reaction. For example, 1 = fastest or most reactive diene, 4 = slowest or least reactive diene.arrow_forwardIf this diene were to be treated with HBr at -10C, where would the Br attach to the structure in the major product?arrow_forwarda. When HBr adds to a conjugated diene, what is the rate-determining step? b. When HBr adds to a conjugated diene, what is the product-determining step?arrow_forward
- Consider the following dienes in a Diels–Alder reaction with ethene. Which will react the fastest? Which will react the slowest? Explainarrow_forwardMaking sure to pay attention to stereochemistry, what is the main product for each reaction?arrow_forwardDraw the products of radical chlorination and bromination of eachcompound. For which compounds is a single constitutional isomerformed for both reactions? What must be true about the structure of areactant for both reactions to form a single product ?arrow_forward
