Question

Question:Draw the organic products formed when 2-bromopentan-3-one ( CH₃CH₂COCHBrCH₃) is treated with each reagent: (a) Li₂CO₃, LiBr, DMF; (b) CH₃CH₂NH₂; (c) CH₃SH.

Short answer

Answer

The major products formed with each reagent are shown below.

Step-by-step solution

Nucleophilic reagents

Reagents, such as ethylamine and methyl mercaptan, are nucleophilic reagents due to the presence of lone pairs over N and S, respectively, that take part in bimolecular nucleophilic substitution reactions.

Strong bases

Lithium carbonate is a strong base that abstracts the most acidic hydrogen via an elimination mechanism. The product obtained from the reaction is an elimination product.

The product obtained from the reaction is a nucleophilic substituted product.
