Match each of the following carboxylic acids to their appropriate pKa values (5.0, 0.2 and 2.7): (A) FCH2COOH (B) (CH3)3CCOOH (C) CF3COOH

Explanation:

Higher the acidic strength  , lower the pKa value.

Among the given acids , CF₃COOH is most acidic because of 3  fluorine atom attached with carbon . fluorine is highly electro-negative electron withdrawing group .

So , acidic strength of given acids will decrease as follows

CF₃COOH > FCH₂COOH > (CH3)₃CCOOH

Hence CF₃COOH will have least pka value ie 0.2

pka value of FCH₂COOH will be 2.7

pka value of (CH3)₃CCOOH will be 5.0

answer; i do believe the correct answer is (river); /// good luck

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
