Arrange the following compounds as directed : (i) In increasing order of solubility in water : (CH_3)_2.NH,CH_(3) NH_(2), C_(6) H_(5)NH_(2) (ii) In decreasing order of basic strength in aqueous solution : (CH_3)_3 N, (CH_3)_2 NH, CH_(3) NH_2 (iii) In increasing order of boiling point : (C_(2) H_(5))_(2) NH, (C_(2) H_(5))_(3)N, C_(2) H_(5) NH_(2)

Arrange the following compounds as directed : (i) In increasing order

1.	Arrange the following compounds as directed : (i) In increasing order of solubility in water : (CH_3)_2.NH,CH_(3) NH_(2), C_(6) H_(5)NH_(2) (ii) In decreasing order of basic strength in aqueous solution : (CH_3)_3 N, (CH_3)_2 NH, CH_(3) NH_2 (iii) In increasing order of boiling point : (C_(2) H_(5))_(2) NH, (C_(2) H_(5))_(3)N, C_(2) H_(5) NH_(2)
Answer» Solution :(i) Increasing order of solubility in water : `C_(6) H_(5) NH_(2) lt (CH_(3) )_(2) NH lt CH_(3) NH_(2)` (II) Decreasing order of basic strength in aqueous solution : `(CH_(3))_(2) NH GT CH_(3) NH_(2) gt (CH_(3))_(3) N` (III) Increasing order of boiling point : `(C_(2) H_(5))_(3) N lt (C_(2) H_(5) )_(2) NH lt C_(2) H_(5) NH_(2)`
