Give the correct order of decreasing basicity of the following compounds. `C_(6)underset((I))(H_(5))NH_(2)" "underset((II))((C_(6)H_(5))_(2))NH" "underset((III))((C_(6)H_(5))_(3))N" "underset((IV))(C_(6)H_(11)NH_(2))`

Most basic among the following is underset(I)(C_(6)H_(5)NH_(2)) underset(II)((C_(2)H_(5))_(2)NH) underset(III)((C_(2)H_(5))_(3)N) underset(IV)(C_(2)H_(5)NH_(2))

The increasing order of the boiling points for the following compound is : underset((I))(C_(2)H_(5))OH " " underset((II))(C_(2)H_(5))Cl " " underset((III))(C_(2)H_(5))CH_(3) " " underset((IV))(C_(2)H_(5))OCH_(3)

Which order is correct for the decreasing reactivity to ring monobromination of the following compounds underset(I)(C_(6)H_(5)CH_(3)), underset(II)(C_(6)H_(5)COOH),underset(III)(C_(6)H_(6)),underset(IV)(C_(6)H_(5)NO_(2))

Compare the basic strength of the following compounds: underset((I))(C_(2)H_(5)O^(-))" "underset((II))(C_(2)H_(5)^(-))" "underset((III))(C_(2)H_(5)NH^(-))" "underset((IV))(NH_(2^(-)))" "underset((V))(F^(-))

The basic of compounds I, II, III and IV underset(I)(CH_(3)NH_(2)), underset(II)((CH_(3))_(2)NH), underset(III)((CH_(3))_(3)N), underset(IV)(C_(6)H_(5)CH_(2)NH_(2)) varies in the order.

Give the correct order of decreasing acidity : C_(2)H_(5)underset((I))SH C_(2)underset((2))(H_(5)OH C_(2)underset((3))(H_(5)NH_(2) CH_(3)underset((4))(CH_(2)CH_(3)
