CHEM 30B Dr. R. Rinehart
Quiz 5: Carboxylic Acids  Study Guide

 1.  IDENTIFY [circle and label] the following functional groups in a given structure:

            acetal, acid anhydride, acyl chloride, alcohol [1o, 2o, 3o], aldehyde, alkyl, alkene, alkyne, aromatic, carboxylic acid, cycloalkyl, disulfide, ester, ether,  halo [specific], hemiacetal, hemiketal, heterocyclic, ketal, ketone, thioester, thiol.

 2.  NAME a given carboxylic acid [which may contain other functional groups such as –OH, -R, -X, -Ar, C=C, C≡C, -OR, -SH]. Be able to match or provide the common name of the common unsaturated and polyunsaturated fatty acids when indicated in shorthand [e.g., C20 D 5,8,11,14]

 3.  DRAW the structure corresponding to a given name.

 4.  PROVIDE the name, structure, or both of the product of a particular reaction [which may not be indicated explicitly] using a given set of reactants.

   

REACTION TYPE

REACTANTS

condensation:

carboxylic acid + alcohol

condensation:

inorganic hydroxy acid + alcohol

hydrolysis:

organic or inorganic ester

saponification:

organic or inorganic ester

ionization [dissociation]:

carboxylic acid

neutralization:

acid + base

reduction:

carboxylic acid

 5.  a.  INDICATE whether or not [and, if so, how] a given molecule is capable of hydrogen bonding with: water; an alcohol; itself [another molecule of the same substance].

       b.  Based on a consideration of the possible intermolecular forces present and their relative strengths and the extent to which they will operate, PREDICT whether or not a given structure will be soluble in: water; cyclohexane.

 6.  ARRANGE a given series of compounds in order of increasing boiling point, based on a consideration of the possible intermolecular forces present and their relative strengths and the extent to which they will operate.

7. DRAW or explain the supramolecular arrangements that soap or detergent molecules can assume in water.

8.  Define or identify key words from the chapter vocabulary.
