MCQ
Which of the following reactions does not yield an amine?
- A$R - X + NH _3 \longrightarrow$
- B$R - CH = NOH +[ H ] \xrightarrow[ C _2 H _2 OH ]{ Na }$
- ✓$R - CN + H _2 O \xrightarrow{ H ^{+}}$
- D$R - CONH _2+[ H ] \xrightarrow{ LiAlH _4}$
✓
Answer
Correct option: C.
$R - CN + H _2 O \xrightarrow{ H ^{+}}$
(c) :
$\begin{array}RR-X+ NH _3 \longrightarrow R- NH _2+ H X \\
R- CH = NOH +4[ H ] \xrightarrow[\mathrm{C}_2 \mathrm{H}_5 \mathrm{OH}]{\mathrm{Na}} R CH _2 NH _2+ H _2 O \\
R- CONH _2+4[ H ] \xrightarrow{ LiAl _4} R CH _2 NH _2+ H _2 O
\end{array}
$
$R- CN + H _2 O \xrightarrow{ H ^{+}} R- COOH$
$\begin{array}RR-X+ NH _3 \longrightarrow R- NH _2+ H X \\
R- CH = NOH +4[ H ] \xrightarrow[\mathrm{C}_2 \mathrm{H}_5 \mathrm{OH}]{\mathrm{Na}} R CH _2 NH _2+ H _2 O \\
R- CONH _2+4[ H ] \xrightarrow{ LiAl _4} R CH _2 NH _2+ H _2 O
\end{array}
$
$R- CN + H _2 O \xrightarrow{ H ^{+}} R- COOH$
