CH_(3)Br+Nu^(-) to CH_(3)-Nu+Br^(-). The decreasing order of the rate of the above reaction with nucleophiles (Nu^(-)) A to D is [Nu^(-)=(A)PhO^(-), (B)AcO^(-), (C)HO^(-), (D)CH_(3)O^(-)]

Answer»

`AgtBgtCgtD`
`BgtDgtCgtA`
`DgtCgtAgtB`
`CgtCgtBgtA`

Solution :The acid character follows the order:
`CH_(3)COOHgtC_(6)H_(5)OHgtH_(2)OgtCH_(3)OH`
The BASIC character will follows the order
`CH_(3)COO^(-)ltC_(6)H_(5)O^(-)ltOH^(-)ltCH_(3)O^(-)`
The stronger the acid, the WEAKER the conjugate base formed.
