Five questions from the pack.
Q1What is the IUPAC name of CH3CH2CONH2?
D. The three-carbon chain with a C(=O)NH2 group is a propanamide. Propanamine would be an amine, propanoic acid has COOH, and N-methylethanamide has a CH3 on nitrogen and only two chain carbons.
Q2Cyclohexanone reacts with a secondary amine (pyrrolidine) and acid catalyst, with water removal. The major product is:
A. A secondary amine has only one N-H, so after forming the carbinolamine it cannot make a neutral C=N and instead loses an alpha proton to give an enamine. Imines come from primary amines, an amide needs an acyl derivative, and an acetal needs two alcohols.
Q3Which species is aromatic?
D. Pyrrole is planar and cyclic with six pi electrons, four from the double bonds and two from nitrogen. Cyclobutadiene (4 pi electrons) and the cyclopentadienyl cation (4) are antiaromatic, and cyclooctatetraene is nonplanar and nonaromatic.
Q4A diterpene contains how many isoprene units?
D. Terpenes are named by units: mono 2, sesqui 3, di 4, tri 6. A diterpene has 20 carbons. Two is a monoterpene, three a sesquiterpene, and six a triterpene such as squalene.
Q5Which compound has the highest boiling point at similar molar mass?
A. A carboxylic acid forms strong hydrogen-bonded dimers, giving a higher boiling point than even the alcohol. The aldehyde and ester cannot donate hydrogen bonds, so they boil lower.
Those are real questions from the pack, word for word.
