1.

The decreasing basic order of the following is: 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 :Acidic: `H_(3) O^(o+) gt CH_(3) COOH gt H_(2)O gt CH_(4)`
BASIC: `H_(2)O LT CH_(3)COO^(o-) lt overset(o-)(O)H lt overset(o-)(C) H_(3)`
