Worked practice questions

Amines are derived by replacing hydrogen atoms of which molecule?

  1. Ammonia
  2. Ammeter
  3. Amylase
  4. Anagram
Show answer and solution

Correct answer: A. Ammonia

1. An amine keeps a nitrogen atom at its centre. 2. The parent compound has that nitrogen bonded to three hydrogens. 3. Amines are derived by replacing hydrogen atoms of an ammonia molecule. 4. The replacements are alkyl or aryl groups. _Source: syllabus Chemistry Part II, Ch 9 'Amines'_

Amines are classified as primary, secondary and tertiary according to the number of:

  1. Hydrocarbons refined
  2. Hydrogens replaced
  3. Hydrogens released
  4. Hydroxides removed
Show answer and solution

Correct answer: B. Hydrogens replaced

1. All three classes contain nitrogen bonded to carbon. 2. What separates them is how many hydrogens of ammonia have gone. 3. They are classified depending upon the number of hydrogen atoms replaced. 4. The replacements are alkyl or aryl groups. _Source: syllabus Chemistry Part II, Ch 9 'Amines'_

The nitrogen orbitals in amines are hybridised in which way?

  1. sp3 hybridised
  2. sp2 hybridised
  3. sp1 hybridised
  4. sp4 hybridised
Show answer and solution

Correct answer: A. sp3 hybridised

1. The nitrogen carries three bonds and one lone pair. 2. Four electron groups around an atom fix the hybridisation. 3. Nitrogen orbitals in amines are sp3 hybridised. 4. So the answer is sp3. _Source: syllabus Chemistry Part II, Ch 9 'Amines'_
