Here the correct order of basic nature is as follows textC text2 textH text5 text- textNH text- textC text2 textH text5 text> textCH text3 text- textCH text2 text- textNH text2 text> textCH text3 text- textCH text= textNH text> textCH text3 text- textC ≡ textN (.i.) Secondary amine is more basic than primary amine. (.ii.) CH3-CH= undersets p2NH ( textiii) ( textCH) text3 - textC¹ ≡ underset textsp textN

Q. Consider the given compounds
$(1)$ $C H_{3} - C H_{2} - N H_{2}$
$(2)$ $C H_{3} - C H = N H$
$(3)$ $C H_{3} - C \equiv N$
$(4)$ $C_{2} H_{5} - N H - C_{2} H_{5}$
Arrange basicity of these compounds in decreasing order:

4 > 1 > 2 > 3

1 > 2 > 3 > 4

1 > 4 > 2 > 3

4 > 1 > 3 > 2

Here the correct order of basic nature is as follows
$C_{2} H_{5} - NH - C_{2} H_{5} > CH_{3} - CH_{2} - NH_{2} > CH_{3} - CH = NH > CH_{3} - C \equiv N$
$(i)$ Secondary amine is more basic than primary amine.
$(ii)$ $C H_{3} - C H = s p^{2} N H$
$(iii) (CH)_{3} - C¹ \equiv sp N$
