Organic Chemistry MCQ with Answers

151) (+)−Glucose and (−)−Fructose can be differentiated by:

Answer is:

Bromine water

Explanation:

Bromine, a mild oxidising agent, oxidises only glucose to gluconic acid. Tollen′′s reagent and Fehling solution being alkaline in nature, cause isomerisation of fructose to glucose. Hence, both of them react with these reagents.

152) Which of the following is not polysaccharide?

Answer is:

Sucrose

153) Benedict′s reagent is reduced by which type of carbohydrates?

Answer is:

Hemiacetals

154) Pick up the false statement:

Answer is:

Glycosides show the phenomenon of mutarotation

155) Amylose is a polymer of:
