Arrange the following in increasing order of their basic strength:
C₂H₅NH₂, C₆H₅NH₂, NH₃, C₆H₅CH₂NH₂ and (C₂H₅)₂NH

Question

Arrange the following in increasing order of their basic strength: C 2 H 5 NH 2 , C 6 H 5 NH 2 , NH 3 , C 6 H 5 CH 2 NH 2 and (C 2 H 5 ) 2 NH

Philoid · Accepted Answer

Alkyl group contribute inductive effect which increases the basic strength of compounds.

NH₃2H₅NH₂<(C₂H₅)₂NH.

Then C₆H₅NH₂ is having –I effect that reduces strength. And C₆H₅CH₂NH₂ increases the basic strength but not as much as C₂H₅ group.

Hence final order will be C₆H₅NH₂36H₅CH₂NH₂2H₅NH₂<(C₂H₅)₂NH.

Arrange the following in increasing order of their basic strength:C2H5NH2, C6H5NH2, NH3, C6H5CH2NH2 and (C2H5)2NH
