Question : 33
Total: 37
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
(i) In increasing order of solubility in water:
(ii) In decreasing order of basic strength in aqueous solution :
(iii) In increasing order of boiling point:
Solution:
(i) Increasing order of solubility:
C 6 H 5 NH 2 < ( CH 3 ) 2 NH < CH 3 NH 2
(ii) Decreasing order of basic strength in aqueous solution:
( CH 3 ) 2 NH > ( CH 3 ) 3 N > CH 3 NH
(iii) Increasing order of boiling point:
( C 2 H 5 ) 3 N < ( C 2 H 5 ) 2 NH < C 2 H 5 NH 2
(ii) Decreasing order of basic strength in aqueous solution:
(iii) Increasing order of boiling point:
