Q3 / 160 · TS EAMCET 2005 · Chemistry

The chemicals and the reaction conditions required for the preparation of ethane are

  • Correct answer
    A
    $\mathrm{C}_2 \mathrm{H}_5 \mathrm{I}, \mathrm{Zn}-\mathrm{Cu}, \mathrm{C}_2 \mathrm{H}_5 \mathrm{OH}$
  • B
    $\mathrm{CH}_3 \mathrm{Cl}, \mathrm{Na}, \mathrm{H}_2 \mathrm{O}$
  • C
    $\mathrm{KOOC}-\mathrm{CH}=\mathrm{CH}-\mathrm{COOK}$, electrolysis
  • D
    $\mathrm{CH}_3 \mathrm{CO}_2 \mathrm{Na}, \mathrm{NaOH}, \mathrm{CaO}, \Delta$

Solution

Alkyl halides can be reduced to hydrocarbons by means of $\mathrm{Zn}-\mathrm{Cu}$ couple in presence of alcohol.

Hence, the correct answer is option: 'A'.
