Question

Determine which is the stronger between the given nucleophiles, using alcohol as the solvent, in the S_N2 reaction. Explain.
(i) CH₃CH₂CH(CH₃)O⁻ or CH₃CH₂CH₂CH₂O⁻
(ii) Br⁻ or F⁻

Accepted Answer

(i) $$CH_{3}CH$$_{2}$$CH_{2}CH$$_{2}$$O^{−}$$; $$CH_{3}CH$$_{2}$$CH_{2}CH$$_{2}$$O^{−} is $$less sterically hindered.(ii) $$Br^{−}$$; $$Br^{−} is $$larger and less electronegative than $$F^{−}.$$

Answer

(i) $$CH_{3}CH$$_{2}$$CH_{2}CH$$_{2}$$O^{−}$$; $$CH_{3}CH$$_{2}$$CH_{2}CH$$_{2}$$O^{−} is $$less electronegative and more hindered.(ii) $$Br^{−}$$; $$Br^{−} is $$larger and less electronegative than $$F^{−}.$$

Answer

(i) $$CH_{3}CH$$_{2}$$CH(CH_{3})O$$^{−}$$; CH$$_{3}$$CH_{2}CH(CH$$_{3}$$)O^{−} is $$more sterically hindered.(ii) $$Br^{−}$$; $$Br^{−} is $$smaller and more electronegative than $$F^{−}.$$
