Concept introduction:
Cycloalkenes on treatment with NBS in CCl4 in the presence of light undergo bromination at the allyl position.
To predict:
The product of the reaction shown.
Answer to Problem 26AP
The products of the reaction shown are
Explanation of Solution
NBS is normally used for allylic bromination. The reaction occurs through a radical mechanism. The radical produced by the homolytic cleavage of the C-H bond in the allyl position gets delocalized with the π electrons of the double bond to yield another radical with an odd electron at the junction of the rings. The attack of bromine radical hence leads to two different products as shown.
The products of the reaction shown are

Interpretation:
The products of the reaction shown are to be predicted.
Concept introduction:
To predict:
The product of the reaction shown.
Answer to Problem 26AP
The products of the reaction shown are N-butyllithium (A) and Lithium n-dibutyl copper (B).
Explanation of Solution
n-Butyl bromide reacts with Li to yield n-butyl lithium and lithium bromide. The n-butyl lithium produced when reacted with CuI yields Lithium n-dibutyl copper as the product.
The products of the reaction shown are N-butyllithium (A) and Lithium n-dibutyl
g)
Interpretation:
The product of the reaction shown is to be predicted.
Concept introduction:
When alkyl halides are treated with lithium dimethyl copper, the halogens are displaced by an alkyl group and a higher alkane is produced as the product.

- Which carbocation is more stable?arrow_forwardAre the products of the given reaction correct? Why or why not?arrow_forwardThe question below asks why the products shown are NOT the correct products. I asked this already, and the person explained why those are the correct products, as opposed to what we would think should be the correct products. That's the opposite of what the question was asking. Why are they not the correct products? A reaction mechanism for how we arrive at the correct products is requested ("using key intermediates"). In other words, why is HCl added to the terminal alkene rather than the internal alkene?arrow_forward
