Which of the following bases is the WEAKEST? The base is followed by its Kb value. Group of answer choices HOCH2CH2NH2, 3.2 × 10-5 (CH3CH2)3N, 5.2 × 10-4 NH3, 1.76 × 10-5 C5H5N, 1.7 × 10-9 Since these are all weak bases, they have the same strength.

C₅H₅N being the weakest base

Explanation:

A weak base (B) is defined as a chemical compound that, in reaction with water, produce a small quantity of BH⁺

The general reaction is:

B + H₂O ⇄ BH⁺ + OH⁻ Where Kb is defined as:

Kb = [BH⁺] [OH⁻] / [B]

That means the smallest Kb is the weakest base because is producing the smallest quantity of BH⁺.

In the problem, the smallest Kb is C₅H₅N being the weakest base.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
