Consider propanoic (CH3CH2CH2CO2H) acid and pentanoic (CH3CH2CH2CH2CO2H) acid and the corresponding alcohols with the same number of carbons, propanol (CH3CH2CH2COH) and pentanol (CH3CH2CH2CH2COH). Select the class of compound that is more soluble. {one answer] Select the best explanation for your answer to the previous question. [a second answer] Group of answer choices a. The solubility of alcohols in water decreases with increasing chain length. b. Propanoic acid and pentanoic acid are more soluble in water than the corresponding alcohol. c. Carboxylic acids are generally more soluble in water than alcohols of the same chain length because of increased hydrogen bonding with the -COOH functional group.  d. Propanol and pentanol are more soluble in water than the corresponding carboxylic acid e. The solubility of carboxylic acids in water decreases with increasing chain length. f. Alcohols are generally more soluble in water than carboxylic acids of the same…

0.1890 grams of an unknown organic acid containing 2 carboxylic groups was dissolved in about 50 mL of water in a 250 mL Erlenmeyer flask and titrated against 0.1000 M NaOH solution using bromothymol blue indicator. 34.62 mL of titrant was used to achieve end point.
