Sugar is a compound that contains $\text{C, H, and O}\text{.}$ If sugar is heated in a flame, it will smoke and turn black. What has happened at the molecular level? What is the black substance?

Interpretation Introduction

Interpretation:

The chemical activity at molecular level and black substance are to be described when sugar is heated in a flame.

Concept introduction:

A sugar molecule consists of carbon, hydrogen, and oxygen atoms. It is a type of disaccharide, which is obtained from the linkage of monosaccharide glucose and fructose.

In a chemical reaction, some chemical bonds are broken by collision in order to form a new molecule. Energy is released during this process.

Explanation of Solution

The atoms of a sugar molecule are linked together in definite arrangements. When a sugar molecule is heated to the point of smoking, it turns black because of chemical changes at the molecular level...
