In the given reaction R - CH_ 2 - COOH Red P+Br_ 2 → A NH_ 3 →...

In the given reaction
\text{R} - {\text{CH}_{2} - \text{COOH}\overset{\text{Red}{\text{P+Br}_{2}}{→} \text{A}\overset{{\text{NH}_{3}}{→} \text{Alanine}
The name of $I^{\text{st}}$ reaction and group $\text{R}$ is -

Step-by-step solution

Alanine is

and product in given reaction is

$$\begin{array}{ll}\text{A} \to \text{R} - \text{CH} - \text{COOH} \\ \text{|} \\ \text{Br}\end{array}$$
So $R = - {CH}_{3}$

$I^{\text{st}}$ reaction is Hell Vohlard Zelinsky reaction.
