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.

Step-by-Step Solution

Answer


Answer

 

The major products formed with each reagent are shown below.




1Step 1: 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.

2Step 2: 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.
