Question: Which compounds can be prepared in good yield by allylic halogenation of an alkene?

a.

b.

c.

Short Answer

Expert verified

Answer

a. Heptane

b. Cannot be made

c. Cannot be made

Step by step solution

01

Halogenation

It involves the treatment of alkene with NBS in the presence of sunlight. The reaction yields the product via allylic substitution.

02

 Step 2: Explanation

a.

The allylic halogenation of cycloheptane forms 3-bromocyclohept-1-ene in a good yield. The reaction is shown below:

Formation of product in a

b.

The given compound can not be made via allylic halogenation method as the starting material (alkene) would produce the mixture of allylic halides.

c.

The given compound can not be made via allylic halogenation method as the starting material (alkene) would produce the mixture of allylic halides.

Question: What alkane is needed to make each alkyl halide by radical halogenation?

Question. Devise a synthesis of OHC(CH2)4CHO from cyclohexane using any required organic or inorganic reagents.

Question: In cells, vitamin C exists largely as its conjugate base X. X is an antioxidant because radicals formed in oxidation processes abstract the labeled H atom, forming a new radical that haltsoxidation. Draw the structure of the radical formed by H abstraction, and explain why this Hatom is most easily removed.

Question: Draw all constitutional isomers formed when X is treated with NBS + hv.
