Question

$C{H}_{3}Br\underset{\text{dry ether}}{\overset{Na}{\to }}X\underset{△}{\overset{(C{H}_{3}COO{)}_{2}Mn}{\to }}Y$

Predict 'X' and 'Y'

• A. X- $HCHO$
  Y- $C{H}_{3}COOH$
• B. X- $C{H}_4$
  Y- $HCHO$
• C. X- $C{H}_3-C{H}_3$
  Y- $C{H}_{3}COOH$
• D. X- $C{H}_3-C{H}_3$
  Y- $HCOOH$

Answer 1

The correct option is C X- $C{H}_3-C{H}_3$

Y- $C{H}_{3}COOH$
In Wurtz reaction, alkane is prepared by reducing alkyl halide using Na in dry ether. It is a coupling reaction where two alkyl group will combine to form higher alkanes.
$R-X+2Na+X-R_1\stackrel{dryether}{⟶}R-R_1+2NaX$.

Controlled oxidationis the process of heating the substance with a regulated supply of $O_2$/air at high pressure, in the presence of a catalyst to produce various oxidation products.
Manganese acetate is an organometallic compound.
The reaction is as follows:
$2C_2{H}_6+3O_2\underset{\Delta }{\overset{(C{H}_{3}COO{)}_{2}Mn}{\to }}2C{H}_{3}COOH+2H_{2}O$

$\therefore$
$C{H}_3-Br\underset{\text{[Wurtz reaction]}}{\underset{\text{dry ether}}{\overset{Na}{}}}C{H}_3-C{H}_3\underset{\text{[controlled oxidation]}}{\underset{△}{\overset{(C{H}_{3}COO{)}_{2}Mn}{}}}C{H}_{3}COOH$
