Q13.
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
Verified 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.
