The decreasing nucelophilic order of the following compoundsis: i. overset(o-)(C)H_(3), ii. Overset(o-)(O)H, iii.CH_(3)COO^(o-), iv. H_(2)O

Answer»

`(i) GT (ii) gt (iii) gt (iv)`
`(iv) gt (iii) gt (ii) gt (i)`
`(iiii) gt (i) gt (ii) gt (iv)`
`(iii) gt (ii) gt (iv) gt (i)`

SOLUTION :Compared to the others, `overset(io-)(C)H_(3)` has different nuclophillic centre, however it belongs to the same period. Basically and nucelophilicity order the same.
`overset(o-)(C)H_(3) gt overset(o-)(O)H gt CH_(3)COO^(o-) gt H_(2)O`
