How many gram of sodium (atomic mass 23 u) is required to prepare one mole of ethane from methyl chloride by Wurtz reaction?
- A 2
- B 23
- C 11.5
- D 46
Answer & Solution
Correct Answer
(D) 46
Step-by-step Solution
Detailed explanation
The Wurtz reaction between methyl chloride and sodium metal in presence of dry ether can be written as:
\(2 CH _3+ Cl +2 Na \xrightarrow{\text { Dryether }} CH _3 \underset{\text { Ethane }}{-} CH _3\) \(+2 NaCl\)
moles of sodium metal reacts to give 1 mole of ethane.
Also,
1 mole of Na metal
2 moles of Na metal
Thus, 46 g of sodium is required to prepare one mole of ethane from methyl chloride by Wurtz reaction.
\(2 CH _3+ Cl +2 Na \xrightarrow{\text { Dryether }} CH _3 \underset{\text { Ethane }}{-} CH _3\) \(+2 NaCl\)
