Identify the alkene obtained as major product in the following Hofmann elimination reaction. $\left(\mathrm{C}_3 \mathrm{H}_7\right) \mathrm{N}^{\oplus}\left(\mathrm{C}_2 \mathrm{H}_5\right)_3 \mathrm{I}^{\ominus} \xrightarrow[\Delta]{\text { mois } \mathrm{A}_2 \mathrm{O}} \mathrm{~A} \xrightarrow[\text { Alkene }+ \text { Amine }]{\Delta}$
  1. Propene
  2. Ethene
  3. But-1-ene
  4. But-2-ene

Solution

$\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CH}_2-\mathrm{N}\left(\mathrm{CH}_2 \mathrm{CH}_3\right)_3 \Gamma^{-}+\mathrm{AgOH}$ N,N,N-triethylpropylammonium iodide
