, PART I (60 %)
1. Carboxylic acids boil at considerably higher temperatures than do alcohols, ketones, or aldehydes of similar
molecular weights. This is because they:
(a) have a greater oxygen content.
(b) are more acidic
(c) form stable hydrogen-bonded dimers.
(d) are hydrophobic.
(e) None of the above
2. The correct priority of functional groups in IUPAC nomenclature is:
(a) ester > amide > ketone > acid.
(b) ketone > acid > ester > amide.
(c) acid > ester > amide > ketone.
(d) amide > ester > acid > ketone.
(e) amide > ester > acid > ketone.
3. Another name for -methoxybutyraldehyde is:
(a) 2-methoxypropanal.
(b) 3-methoxypropanal.
(c) 2-methoxybutanal.
(d) 3-methoxybutanal.
(e) 2-methoxypentanal.

(a) p-nitrobenzoic acid (pKa = 3.41)
(b) acetic acid (ethanoic acid; pKa = 4.74)
(c) hexanoic acid (pKa = 4.88)
(d) octanoic acid (pKa = 4.89
