The decreasing nucleophillic order fo the following compounds is: i. F^(o-), ii. Cl^(o-), iii. Br^(o-), Iv. I^(o-)

Answer»

`(i) gt (II) gt (iii) gt (IV)`<BR>`(iv) gt (iii) gt (ii) gt (i)`
`(ii) gt (i) gt (iii) gt (iv)`
`(ii) gt (i) gt (iv) gt (iii)`

Solution :SINCE nucleopphilic centre is different and they belong to the same group, so BASIC character and nuclophilicy are reversed.
`I^(o-) gt Br^(o-) gt Cl^(o-) gt F^(o-)`
