Question
Which of the following reactions are feasible?
Options
\[\ce{CH3CH2Br + Na^{+}O^{-}C(CH3)3 -> CH3CH2 - O - C(CH3)3}\]
\[\ce{(CH3)3 C - Cl + Na^{+}O^{-}CH2CH3 -> CH3CH2 - O - C(CH3)3}\]
Both \[\ce{CH3CH2Br + Na^{+}O^{-}C(CH3)3 -> CH3CH2 - O - C(CH3)3}\] and \[\ce{(CH3)3 C - Cl + Na^{+}O^{-}CH2CH3 -> CH3CH2 - O - C(CH3)3}\]
Neither \[\ce{CH3CH2Br + Na^{+}O^{-}C(CH3)3 -> CH3CH2 - O - C(CH3)3}\] nor \[\ce{(CH3)3 C - Cl + Na^{+}O^{-}CH2CH3 -> CH3CH2 - O - C(CH3)3}\]

Solution
\[\ce{CH3CH2Br + Na^{+}O^{-}C(CH3)3 -> CH3CH2 - O - C(CH3)3}\]
Explanation:
The above reaction is an example of Williamson synthesis. In this process, an alkyl halide is allowed to react with sodium alkoxide. The reaction involves the SN2 attack of an alkoxide ion on a primary alkyl halide.
