Textbook Question
Chapter 10, Problem 19P
Explain the relative distribution of produces below using reaction energy diagrams for the hydrogen abstraction step that leads to each product. (The rare-determining seep in radical halogenation is the hydrogen abstraction step.) In energy diagrams for the two pathways, show die relative energies of the transition scares and of the alkyl radical intermediate char results in each case.

Both questions related to each other. Need solution for both with explanation
The high reactivity of alkyl halides can be explained in terms of nature of C-X bond which is highly polarized
covalent bond due to large difference in the electronegativities of carbon and halogen atom. This polarity
is responsible for the nucleophilic substitution reactions of alkyl halides which mostly occur by Swa and Swa
mechanisms. Sy reaction is a two-step process and in the first step, R-X ionizes to give carbocation (slow
process). In the second step, the nucleophile attacks the carbocation from either side to form the product
(fast process). In Swi reaction, there can be racemization and inversion. Swi reaction is favored by heavy
(bulky) groups on the carbon atom attached to halogens. i.e., R,C-X>R;CH-X>R-CH,X>CH,X. In Sna reaction,
the strong nucleophile OH attacks from the opposite side of the chlorine atom to give an intermediate
(transition state) which breaks to yield the product (alcohol) and leaving (X) group. The alcohol has a
configuration opposite to that of the…

In the case of conjugated dienes, that is dienes that are separated by one sigma bond, the carbocation that is formed is stabilized additionally by resonance. Addition of the nucleophile to the carbocation intermediate can therefore give two types of products: direct addition to the double bond, also called 1,2-addition, and conjugate addition to the resonance stabilized carbocation, also called 1,4-addition.Allylic carbocation stability is affected by both the nature of the carbocation (primary allylic, secondary allylic, or tertiary allylic) and by the degree of substitution of the double bond. The latter is typically the dominant effect and so a primary allylic carbocation with a trisubstituted double bond is more stable than a tertiary allylic carbocation with a monosubstituted double bond.Electrophilic addition to a conjugated diene is…arrow_forward
