1.

The decarising basic order of the following is: i. F_(3)CSO_(3)^(o-), ii. Cl_(3)C-COO^(o-) iii. PhSO_(3)^(o-), iv. MeSO_(3)^(o-)

Answer»

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

SOLUTION :Stronger the ACI, WEAKER the `C_(B)`
i. Sulphonic acids are stronger than carboxylic acids.
ii. Aromatic sulphonic acids are stronger than alipatic sulphonic acids.
iii. More the number of number of `EWG` stronger is the acid.
Acidic:
`F_(3) CSO_(3)H gt PhSO_*3)H gt MeSO_(3)^(o-) lt MeSO_(3)H gt Cl_(3)CCOOH`
Basic:
`F_(3)CSO_(3)^(o-) lt PhSO_(3)^(o-) lt MeSI_(3)^(o-) lt Cl_(3)CCO overset(o-)(O)`
