Question: Show the products you expect when each compound reacts with NBS with light shining on the reaction.

c)

Short Answer

Expert verified

c)The product formed from the above compound when react with NBS

Step by step solution

01

Step 1:

The bromination reaction is the process by which one or more bromine atoms are added to a chemical. Halogination reaction includes bromination reactions. N-bromosuccinimide, also known as NBS (sourse of Br), is employed in this reaction as a reagent to aid in radical substitution.

A free radical is a molecule that lacks charge and has an unpaired electron. Free radicals are extremely reactive substances with a brief shelf life.

02

Step 2:

First, the reagent N-bromosuccinimide (NBS) that produces the bromine radical Br undergoes radical formation.

03

Step 3:

An allylic free radical is the end product of the formation of free radical in the alkene. The proposed mechanism to explain the observed products in the described reaction between an alkene and NBS.

Question:

  1. Why do most long-chain fatty acids show a large peak in the mass spectrum at m/z 60 ?
  2. Use equations to explain the prominent peaks at m/z 74 and m/z 87 in the mass spectrum of 2-methylpentanoic acid.
  3. Why doesnโ€™t the mass spectrum of 2-methylpentanoic acid show a large peak at m/z 60 ?

Grignard reagents add to carbonate esters as they add to other esters.

(a) Predict the major product of the following reaction.

(b) Show how you would synthesize 3-ethylpentan-3-ol using diethyl carbonate and ethyl bromide as your only organic reagents.

(c) Diethyl carbonate is a liquid reagent that is easy to handle. In contrast, phosgene is a highly toxic and corrosive gas. Show how you might use diethyl carbonate instead of phosgene to make Lexanยฎ. Also, show how you might use diethyl carbonate instead of methyl isocyanate to make Sevinยฎ insecticide.

Most of the Fischer esterification mechanism is identical with the mechanism of acetal formation. The difference is in the final step, where a resonance-stabilized carbocation loses a proton to give the ester. Write mechanisms for the following reactions, with the comparable steps directly above and below each other. Explain why the final step of the esterification (proton loss) cannot occur in acetal formation, and show what happens instead.
