Worked practice questions

Glucose is an aldohexose also known as:

  1. Dextrose
  2. Lactose
  3. Maltose
  4. Sucrose
Show answer and solution

Correct answer: A. Dextrose

1. It has six carbons and an aldehyde group. 2. It is the monomer of starch and cellulose. 3. Its common name is dextrose. _Source: syllabus Chemistry Part 2, Unit 10 'Biomolecules'_

Prolonged heating of glucose with hydrogen iodide gives:

  1. Normal butane
  2. Normal hexane
  3. Normal heptane
  4. Normal pentane
Show answer and solution

Correct answer: B. Normal hexane

1. The reduction strips every oxygen from the molecule. 2. What is left shows how the carbons are joined. 3. Normal hexane proves a straight six carbon chain. _Source: syllabus Chemistry Part 2, Unit 10 'Biomolecules'_

Glucose oxidised by bromine water yields:

  1. Glyceric acid
  2. Glycolic acid
  3. Gluconic acid
  4. Glutamic acid
Show answer and solution

Correct answer: C. Gluconic acid

1. Bromine water is a mild oxidising agent. 2. It attacks only an aldehyde group. 3. The six carbon acid formed is gluconic acid. _Source: syllabus Chemistry Part 2, Unit 10 'Biomolecules'_
