Worked practice questions

The group written as CHO is the:

  1. Aldehyde group
  2. Alkaline group
  3. Anhydride group
  4. Aluminate group
Show answer and solution

Correct answer: A. Aldehyde group

1. Each functional group has its own formula. 2. The CHO group is the aldehyde group. 3. So the correct answer is aldehyde group. _Source: syllabus Chemistry Part II, Unit 12 'Organic Chemistry: Some Basic Principles and Techniques'_

The group written as COOH is the:

  1. Carbamic acids
  2. Carboxylic acid
  3. Carbolic acids
  4. Carbonic acids
Show answer and solution

Correct answer: B. Carboxylic acid

1. This group defines a whole family of organic acids. 2. The COOH group is the carboxylic acid group. 3. So the correct answer is carboxylic acid. _Source: syllabus Chemistry Part II, Unit 12 'Organic Chemistry: Some Basic Principles and Techniques'_

Compounds sharing a characteristic functional group form a:

  1. Homozygous series
  2. Homophonic series
  3. Homologous series
  4. Homogenous series
Show answer and solution

Correct answer: C. Homologous series

1. Organic compounds are classified into families. 2. A group of compounds each containing a characteristic functional group forms a homologous series. 3. So the correct answer is homologous series. _Source: syllabus Chemistry Part II, Unit 12 'Organic Chemistry: Some Basic Principles and Techniques'_
