What will be the decreasing order of basic strength of the following conjugate bases? ( ⁻ OH , R O , CH ₃ CO O , C I )

Options

  1. A( R O > ⁻ OH > CH ₃ CO O > C I )
  2. B( C l > R O > ⁻ OH > CH ₃ CO O )
  3. C( ⁻ OH > R O > CH ₃ CO O > C 1 )
  4. D( C I > ⁻ OH > R O > CH ₃ CO O )

Correct answer

A. ( R O > ⁻ OH > CH ₃ CO O > C I )

Step-by-step solution

Strong acid have weak conjugate base Acidic strength : H - Cl > CH ₃ COOH > H ₂ O > R - OH Conjugate base strength : Cl ⁻ < CH ₃ COO ⁻ < O H < RO ⁻
