question_answer 25)

Arrange the compounds of each set in order of reactivitytowards  displacement: (i) 2-bromo-2-methylbutane, 1-bromopentane, 2-bromopentane (ii) 1-bromo-3-methylbutane, 2-bromo-2-methylbutane, 2-bromo-3-methylbutane (iii) 1-bromobutane, 1-bromo-2, 2-dimethylpropane, 1-bromo-2-methylbutane, 1-bromo-3-methylbutane. reactions involve the formation of transition state. Higher the steric hindrance, lesser the stability of transition state and so lesser the reactivity towards .  

Answer:

The order of decreasing reactivity of compounds is given as (i) (ii) (iii)
