The correct order of basictiies of the following compounds is : . 3. (CH_(3))_(2)NH. 4. CH_(3)-overset(O)overset(||)(C)-NH_(2)

Answer»

`(2) GT (1) gt (3) gt (4)`
`(1) gt (3) gt (2)gt (4)`
`(3) gt (1) gt (2) gt (4)`
`(1) gt (2) gt (3) gt (4)`

Solution :`(1) gt (3) gt (2)gt (4)`.
1.` (##KSV_CHM_ORG_P2_C15_E01_152_S01.png" width="80%"> LTBRGT More basci due to the presence of two ` LP overlinee^, s` on each (N).
2.` EtNH_2`, Due to `+I` effect of (Et) group , but `+ I` effect to two Me groups is greater than `+I` effect of `(Et)` group. Hence (3) is more basic than (2).
3.`(CH_3)_2 NH`. Due to `(+I)` effect of two Me groups.
4.` (##KSV_CHM_ORG_P2_C15_E01_152_S02.png" width="80%">
(Amides are resonance STABILISED , so they are the weakest base , Amides behalve as amphoteric ).
