8 questions from the practice bank, spread across the chapter's topics. The full set is in the app.
Question 2: Preparation and Reactions of Amines
Azo dyes are prepared by:
- A reducing nitro compounds with zinc
- B coupling a diazonium salt with a phenol or an aromatic amine
- C hydrolysing esters
- D oxidising amines
Answer: B. coupling a diazonium salt with a phenol or an aromatic amine
Why: Their –N=N– group gives them their colour.
Question 3: Classification and Basicity of Amines
Among isomeric amines, the order of boiling points is:
- A secondary > primary > tertiary
- B tertiary > secondary > primary
- C all equal
- D primary > secondary > tertiary
Answer: D. primary > secondary > tertiary
Why: Primary amines have two N–H bonds for hydrogen bonding.
Question 4: Preparation and Reactions of Amines
Direct nitration of aniline gives a considerable amount of the meta product because:
- A the –NH₂ group is meta-directing
- B in the strongly acidic medium aniline is protonated to the anilinium ion, which is meta-directing
- C nitric acid is a weak acid
- D the ring has no π electrons
Answer: B. in the strongly acidic medium aniline is protonated to the anilinium ion, which is meta-directing
Why: Protecting the group by acetylation gives the para product.
Question 5: Classification and Basicity of Amines
Amines have lower boiling points than alcohols of similar molar mass because:
- A nitrogen is less electronegative than oxygen, so the N–H···N hydrogen bonds are weaker
- B amines are ionic
- C amines have a larger size
- D amines have no lone pair
Answer: A. nitrogen is less electronegative than oxygen, so the N–H···N hydrogen bonds are weaker
Why: Both are capable of hydrogen bonding.
Question 6: Preparation and Reactions of Amines
Aryl diazonium salts are more stable than alkyl diazonium salts because of:
- A steric hindrance
- B resonance, which delocalises the positive charge into the benzene ring
- C inductive effect
- D hyperconjugation
Answer: B. resonance, which delocalises the positive charge into the benzene ring
Why: Even so, they are used in solution at 273–278 K.
Question 7: Classification and Basicity of Amines
The IUPAC name of (CH₃)₂NH is:
- A methylethanamine
- B N-methylmethanamine
- C dimethylamine only
- D dimethylammonia
Answer: B. N-methylmethanamine
Why: The secondary amine is named as an N-substituted primary amine.
Question 8: Preparation and Reactions of Amines
Bromination of acetanilide gives mainly:
- A o-bromoacetanilide only
- B m-bromoacetanilide
- C 2,4,6-tribromoacetanilide
- D p-bromoacetanilide
Answer: D. p-bromoacetanilide
Why: The acetyl group reduces the activating effect of the nitrogen.
