5 FINAL TEST 2026 QUESTIONS WITH
CORRECT ANSWERS GRADED A+
◍ solubility decreases.
Answer: As the size of the alkyl groups attached to the nitrile group
increases, what happens to the solubility?
◍ Hydrogen bonding and VDWFs are classified as what?.
Answer: Nonbonding intermolecular forces
◍ Van der Waals forces (VDWFs).
Answer: attractive forces between non-polar molecules
◍ ethanamide/ acetamide.
Answer: What is the name of this structure?
◍ quaternary ammonium salt.
Answer: what does a tertiary amine alkylate to?
◍ Amide Structure.
Answer: O=C-NH2
◍ tertiary amines do not have NH bonds to substitute an R-C=O bond for a
hydrogen.
Answer: why cant 3rd degree amines undergo nucleophilic acyl
substitution?
◍ Ether structure.
Answer: R-O-R
◍ basic and nucleophilic.
Answer: are amines acidic or basic?
, ◍ a less reactive acid derivative.
Answer: what can you convert more reactive acid derivatives to?
◍ water and alcohol (H from these attaches to lone pair of N on nitrile).
Answer: what molecules can hydrogen bond to nitriles?
◍ Thioether Structure.
Answer: R-S-R
◍ amides.
Answer: nucleophilic acyl substitution turns ammonia and amines into?
◍ Hydrocarbons.
Answer: Molecules composed of only hydrogen and carbon
◍ primary amine.
Answer: R-NH2
◍ name amine as N-substituted where largest compound = parentname other
groups as N-alkyl substituents.
Answer: naming unsymmetrically substituted 2nd and 3rd degree amines
◍ Poleyenes.
Answer: Compounds with more than one double bond
◍ Thiol Structure.
Answer: R-SH
◍ Heptane.
Answer: C's: 7MF: C7H16SF: CH3(CH2)5CH3Isomer: 9
◍ Polyalkylation: yield a mix of amine products because no reaction stops
cleanly after a single alkylation.
Answer: what is the disadvantage of alkylation of amines?
◍ Pentane.
Answer: C's: 5MF: C5H12SF: CH3(CH2)3CH3Isomers: 3
◍ substituent.
Answer: an atom or group of atoms that can take the place of a hydrogen
