Which of the molecules below is the strongest base?

CH3O-

(CH2)2N-

Cl-

HO-

(CH3)2NH

Expert Solution

Among the following the strongest base is

Reason :

The dissociation of methanol is given as follows

As methanol is very weak acid therefore its conjugate base will be very strong base.

For

As HCl is the strong acid hence the conjugate base is weak base.

For

As is weak base hence it will give strong conjugate acid

Dimethylamine, (CH3)2NH, is an organic base with pKb= 3.23at 298 K. In an experiment, a 40.0 mL sample of 0.105mol/L-1(CH3)2NH(aq)is titrated with 0.150mol/L-11HI(aq)at 298 K. (a) Write a balanced chemical equation for the neutralization reaction upon which this titration is based, and indicate clearly which atom is being protonated. Then, calculate the equilibrium constant for the neutralization reaction. (Hint: To calculate the equilibrium constant, you may find it helpful to represent the neutralization reaction as the sum of twoor morereactions.)...
