Justify and arrange the following compounds of each set in increasing order of reactivity towards the asked displacement : 1-Bromobutane, 2-Bromobutane, 2-Bromo-2-Methylpropane (S_(N)2 reaction)

Answer»

SOLUTION :2-Bromo-2-Methylpropane `lt` 2-Bromobutane `lt` 1-Bromobutane
The nucleophile faces the MAXIMUM hindrance from the BULKY GROUPS in 2-Bromo-2Methylpeopane followed by 2-Bromobutane and 1-Bromobutane. Hence the above order.
