Which one of the followng reactions will not lead to the desired ether formation in major proportion? (iso-Bu \Rightarrow isobutyl, sec-Bu \Rightarrow sec-butyl, {\nPr} \Rightarrow n-propyl, { ^\t{\Bu}} \Rightarrow tert-butyl, Et \Rightarrow ethyl) [8 Apr 2025 Shift 2]

Correct Answer is : iso-Bu O+Na+ sec-BuBr ⟶ sec-Bu-O-iso-Bu

iso-Bu \overline{ {\O}} { {\Na}}^{+}+ sec-BuBr \rightarrow sec-Bu-O-iso-Bu

{ }^t {\Bu} \overline{ {\O}} { {\Na}}^{+}+ {\EtBr} \rightarrow{ }^t {\Bu}- {\O}- {\Et}

\overline{ {\O}} { {\Na}}^{+}+ {\CH}_3 {\Br} \rightarrow {\O}- {\CH}_3

{ {\Na}}^{+} \overline{ {\O}} + {\n}- {\PrBr} \rightarrow {\n}- {\Pr}- {\O}
