Identify the number of moles of ethene obtained when n moles of $\mathrm{N}, \mathrm{N}, \mathrm{N}$-triethylpropylammonium iodide is treated with moist $\mathrm{Ag}_2 \mathrm{O}$ and then heated.

• Correct answer
  A

  n
• B

  2 n
• C

  3 n
• D

  4 n

Solution

1 mole of $\mathrm{N}, \mathrm{N}, \mathrm{N}-$ triethylpropylammonium iodide gives 1 mole of ethane. Thus, n mole N,N,N-triethylpropylammonium iodide will give n mole of ethane. $\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CH}_2-\mathrm{N}\left(\mathrm{CH}_2 \mathrm{CH}_3\right)_3 \mathrm{\Gamma}+\mathrm{AgOH}$

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