उत्तर
SN2 reaction involves the formation of transition state. Therefore, reactivity towards SN2 depends upon the steric hindrance:
Due to the presence of 2 methyl group in 2-Bromo-2-methylbutane it is least reactive towards SN2 reactions, 2-bromopentane is moderately reactive while 1-bromopentane is most reactive.
2-Bromo-2-methylbutane < 2-Bromopentane < 1-Bromopentane
