The decreasing nucleophilic order of the following compounds is: i. PhSO_(3)^(o-), ii. C_(2)H_(5)SO_(3)^(o-), iii. C_(2)H_(5)COO^(o-), iv. overset(o-)(C)N, v. overset(o-)(O)H

Answer»

`(v) gt (iv) gt (III) gt (ii) gt (i)`
`(i) gt (ii) gt (iii) gt (iv) gt (v)`
`(iv) gt (v) gt (iii) gt (ii) gt (i)`
`(i) gt (ii) gt (iii) gt (v) gt (iv)`

SOLUTION :Nucelphilic centre on `overset(o-)(C)N` is different from others, but belongs to the same period. Basic and nucelophilic ORDERS are same.
