Give the order of reactivity towards SN^(2) reaction of the followig: a. i. 1- Bromopentane ii. 2- Bromopenatane iii. 2- Bromo -2 methyl butane b. i. n- Butybromide (C_(4) H_(9) Br) ii. Isobutyl bromide Me_(2) CHCH_(2)Br iii. sec- Buityl bromnide CH_(3) - CH(Me) CH_(2)Br iv. tert- Butyl bromide Me_(2)C-Br

Answer»

SOLUTION :a. `(i) gt (II) gt (iii) (1^(@) gt 2^(@) gt 3^(@))`
b. `(i) gt (ii) gt (iii) gt (IV). SN^(2)` is slow for large `G` in `G - CH_()X`.
