The major product of the reaction between ter-butyl chloride and sodium ethoxide is:
1 2-Methyl prop - 1 - ene
2 1 - Butene
3 2 - Butene
4 Ethene
Explanation:
Tertiary alkyl halides undergo elimination when treated with strong bases like sodium ethoxide.

In the Williamson synthesis of ethers given by the general equation \(\mathrm{R}-\mathrm{X}+\mathrm{R}^{1} \mathrm{ONa} \longrightarrow \mathrm{R}-\mathrm{O}-\mathrm{R}^{1}\). The yield form \(\mathrm{R}-\mathrm{X}\) follows the sequence
1 \(\mathrm{CH}_{3}>1^{0}>2^{0}>3^{0}\)
2 \(\mathrm{CH}_{3} < 1^{0} < 2^{0} < 3^{0}\)
3 \(\mathrm{CH}_{3} < 1^{0}>2^{0}>3^{0}\)
4 \(\mathrm{CH}_{3}>1^{0} < 2^{0} < 3^{0}\)
Explanation:
\(3^\circ \,\,{\text{RX}}\) produces alkene with \(\mathrm{R}^{1} \mathrm{ONa}\) instead of ethers.
