Determine which is the stronger between the given nucleophiles, using alcohol as the solvent, in the SN2 reaction. Explain.
(i) CH3CH2CH(CH3)O− or CH3CH2CH2CH2O−
(ii) Br− or F−
(i) CH3CH2CH2CH2O−; CH3CH2CH2CH2O− is less electronegative and more hindered.
(ii) Br−; Br− is larger and less electronegative than F−.
(i) CH3CH2CH(CH3)O−; CH3CH2CH(CH3)O− is more sterically hindered.
(ii) Br−; Br− is smaller and more electronegative than F−.
