CHXI13:HYDROCARBONS

317983 The conversion of ethylene into ethane can be effected by :

1 Nascent hydrogen

2

Zn + HCl

3 Raney nickel and hydrogen

4 Clemmensen reduction

CHXI13:HYDROCARBONS

317984 The alkane formed on heating sodium butanoate with sodalime is

1 methane

2 ethane

3 propane

4 butane

Explanation:

$\underset{Sodium butanoate}{C H_{3} C H_{2} C H_{2} CO O^{-} N a^{+}} + NaOH \to_{Δ}^{CaO}$
$\underset{Propane}{C H_{3} C H_{2} C H_{3}} + N a_{2} C O_{3}$

CHXI13:HYDROCARBONS

317985 By which one of the following compounds both ${CH}_{4}$ and ${CH}_{3} - {CH}_{3}$ can be prepared in one step ?

1

{CH}_{3} I

2

{CH}_{3} OH

3

{CH}_{3} {CH}_{2} I

4

C_{2} H_{5} OH

Explanation:

Methane and Ethane can be prepared in one step from ${CH}_{3} I$ by reduction with $Zn - Cu / H_{2} O$ and Wurtz reaction [Which double the number of $C$ -atoms] respectively.
