Arrange the following in the decreasing order of basic strength: `CH_(3)CH_(2)CH_(2)NH_(2), CH_(2) = CH- CH_(2)NH_(2) and CH -= - CH_(2) NH_(2)`

Text Solution

Verified by Experts

The order of basic strength is : `CH_(3)CH_(2)CH_(2)NH_(2) gt CH_(2)=CH-CH_(2)NH_(2) gt CH= C CH_(2)NH_(2)`
Alkyl group is electron releasing and stabilises the conjugate acid of propyl amine. Alkenyl and alkynyl groups connected to `-CH_(2)NH_(2)` are electron withdrawing group and destabilise the conjugate acid of `CH_(2)=CHCH_(2)NH_(2)` and `CH-=C CH_(2)NH_(2)`, hence they become weak base.
