Carboxylic Acids and their Derivatives - Result Question 56
####42. Complete the following sequence of reactions with appropriate structures
$$ \begin{array}{r} CH _3-CH _2-COOH \xrightarrow[Br _2]{Red-P} A \ A \xrightarrow[\text { (ii) } H^{+} KOH \text { (excess) }]{\longrightarrow} B \end{array} $$
$(1995,2 M)$
Show Answer
Solution:
- $CH _3 CH _2 COOH \xrightarrow[Br _2]{\text { red- } P} \underset{A}{CH _3}-\underset{Br}{CH}-COOH$ (HVZ reaction)
$$ \xrightarrow[\text { (ii) } H^{+}]{\text {(i) alc. } KOH} CH _2=\underset{B}{CH}-COOH $$
