Chapter 23, Problem 64A

Interpretation Introduction

Interpretation:

The occurrence of following misconception should be explained.

As the name denotes, carbohydrates are not hydrates of carbon.

Concept introduction:

A biological molecule which consists of carbon, hydrogen and oxygen is known as carbohydrates. The general formula of carbohydrate is ${{\text{(CH}}_{\text{2}}\text{O)}}_{\text{n}}$.

Explanation of Solution

The general formula of carbohydrate is ${{\text{(CH}}_{\text{2}}\text{O)}}_{\text{n}}$ which consist of carbon atom(s), hydrogen atom(s) and oxygen atom(s).

In the general formula of carbohydrate, n represents number of atoms. Carbohydrates are not hydrates of carbon as there is not water molecule is present. In carbohydrates, carbon atoms are linked with hydrogen atoms and hydroxyl groups which is a component of water.

Initially, scientist develops a concept that carbohydrates are hydrates of carbon. After different analysis, it is found that no water molecule is present in carbohydrates, they consist of sugar molecules. Thus, carbohydrates are not hydrates of carbon.
