Sample questions

1. Which of the following BEST describes the amphoteric nature of alkanols?

a.They can act as both acids and bases due to the ability of the O-H bond to split in two ways.

b.They can only act as bases by accepting a proton at the oxygen atom.

c.They can only act as acids by donating a proton from the hydroxyl group.

d.They are neutral compounds that do not show any acidic or basic properties in solution.

2. What is the IUPAC name of the compound with the structure CH₃CH(OH)CH₂CH(CH₃)CH₃?

a.2-methylhexan-4-ol

b.2-methylpentan-4-ol

c.4-methylhexan-2-ol

d.4-methylpentan-2-ol

3. Which of the following statements about the acidity of alcohols and phenols is TRUE?

a.Acidity increases with an increase in the number of alkyl groups on the carbon bearing the -OH.

b.Phenol is the most acidic because the phenoxide ion is stabilized by resonance.

c.Tertiary alkanols are more acidic than primary alkanols due to hyperconjugation.

d.Phenol is less acidic than methanol because the alkyl group is electron-withdrawing.

4. In the nitration of phenol, the major products are ortho- and para-nitrophenol. Which of the following BEST explains this observation?

a.The meta position is sterically hindered by the hydroxyl group, preventing substitution there.

b.The reaction is carried out at high temperature, which favors ortho and para substitution.

c.The nitro group is an ortho-para director, forcing substitution at these positions.

d.The hydroxyl group is an ortho-para director due to its strong activating and electron-donating effect.

5. The Cope reaction involves the thermal elimination of a tertiary amine oxide to form an alkene. What is the primary driving force for this reaction?

a.The formation of a volatile amine and a stable alkene.

b.The formation of a highly stable nitrile compound.

c.The formation of a strong N-O bond in the product.

d.The formation of a stable carbocation intermediate.
