A) I > II > III
B) I > II > III
C) II > III > I
D) III > II > I
Correct Answer: A
Solution :
[a]Basic nature of a compound depends upon the ease with which it can donate its unshared pair of electrons. |
I. electron donating group. (Maximum basic) |
II. electron withdrawing. The lone pair of N is involved in resonance with \[C{{H}_{3}}CO.\] |
III. Lone-pair of N-atom is also used in delocalization of \[\pi -\]electrons, resonance of carbonyl benzene nucleus (least basic) |
Thus, the correct order of basic nature of given compounds are as follows: I > II > III. |
