Question

Which of the following reactions does not yield an amine? (A) R - X + NH3 xrightarrow 373 K (B) R - CH = NOH + [H] xrightarrow[C2H5OH]Na (C) R - CN + H2O xrightarrowH+ (D) R - CONH2 +4[H] xrightarrowLiAlH4

R - X + NH3 xrightarrow 373 K R - NH2 + HX R - CH = NOH + 4 [H] xrightarrow[C2H5OH]Na RCNH2NH2 + H2O R - CONH2 +4[H] xrightarrowLiAlH4RCNH2NH2 + H2O But, R - CN + 2H2O xrightarrowH+ R COOH + NH3

Q. Which of the following reactions does not yield an amine?

$R - X + N H_{3} 373 K$

$R - C H = NO H + [H] N a C_{2} H_{5} O H$

$R - CN + H_{2} O H^{+}$

$R - CON H_{2} + 4 [H] L i A l H_{4}$

$R - X + N H_{3} 373 K R - N H_{2} + H X$
$R - C H = NO H + 4 [H] N a C_{2} H_{5} O H$
$RCN H_{2} N H_{2} + H_{2} O$
$R - CON H_{2} + 4 [H] L i A l H_{4} RCN H_{2} N H_{2} + H_{2} O$
But, $R - CN + 2 H_{2} O H^{+} RCOO H + N H_{3}$

R−X+NH3​373K​

R−CH=NOH+[H]NaC2​H5​OH​

R−CN+H2​OH+​

R−CONH2​+4[H]LiAlH4​​

$R - X + N H_{3} 373 K$

$R - C H = NO H + [H] N a C_{2} H_{5} O H$

$R - CN + H_{2} O H^{+}$

$R - CON H_{2} + 4 [H] L i A l H_{4}$

$R - X + N H_{3} 373 K R - N H_{2} + H X$
$R - C H = NO H + 4 [H] N a C_{2} H_{5} O H$
$RCN H_{2} N H_{2} + H_{2} O$
$R - CON H_{2} + 4 [H] L i A l H_{4} RCN H_{2} N H_{2} + H_{2} O$
But, $R - CN + 2 H_{2} O H^{+} RCOO H + N H_{3}$
