Draw the structure of the product of each step in the following three-step synthesis. Show the formal charges, if applicable. As
a start, the benzene ring is drawn for you in each product. Although the first step produces a mixture of isomers, the para isomer is isolated as the sole product of interest and used in the second step. Give only the major product for the second and third steps.
1 answer:
Answer:
Second step: 4-bromo-1-methyl-2-nitrobenzene.
Third step: 1.5-dibromo-2-methyl-3-nitrobenzene.
Explanation:
To solve this exercise I will use the concepts of electrophilic substitution. In these reactions, a functional group is displaced by an electrophile. In the attached image are the two main products.

Answer:
31.3 kJ/mol is the free energy, ΔG, for the overall reaction, A⇌D.
Explanation:
A⇌B, = 11.9 kJ/mol ...[1]
B⇌C, = -26.7 kJ/mol ...[2]
C⇌D, = 7.30 kJ/mol ...[3]
A⇌D, = ?...[4]
[4] = [1] - [2] - [3] (Using Hess's law)
31.3 kJ/mol is the free energy, ΔG, for the overall reaction, A⇌D.
