The decreasing basic order of the following 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 :ACIDIC: `PhSO_(3)H gt C_(2)H_(5)SO_(3)H gt C_(2)H_(5)COOH gt HCN gt H_(2)O`
BASIC:
`PhSO_(3)^(o-) lt C_(2)H_(5)SO_(3)^(o-) lt C_(2)H_(5)COO^(o-) lt overset(o-)(C)N lt overset(o-(O)H`
