  General, Organic, and Biological Chemistry - 4th edition, Chapter 2, Problem 17P , additional homework tip  1

Concept Introduction:

Molecular art is defined as the art that showcases molecules as physical objects that have a definite shape and size. According to molecular art, some of the atoms are represented with a particular color as follows:

A carbon atom is represented by a black colored sphere.

The oxygen atom is represented by a red-colored sphere.

The nitrogen atom is represented by a blue-colored sphere.

The hydrogen atom is represented by a white-colored sphere.

Chlorine atom is represented by a green-colored sphere.

Bromine atom is represented by a brown-colored sphere.

Answer to Problem 17P

There are two molecules of CO , one molecule of CO2 and one molecule of O2 . So, there are only carbon and oxygen elements in the given molecular art.

Explanation of Solution

In the given space-filling model, there are black and red spheres. Black spheres correspond to the element carbon whereas red spheres correspond to the element oxygen.

Therefore, two molecules contain one carbon atom and one oxygen atom each. Hence, its molecular formula is CO . This means that there are two molecules of CO.

Another, one molecule contains one carbon and two oxygen atoms. Hence, its molecular formula is CO2.

Another molecule contains only two oxygen atoms. Therefore, its molecular formula is O2.

The hydrogen atom is represented by a white-colored sphere.

Chlorine atom is represented by a green-colored sphere.

Bromine atom is represented by a brown-colored sphere.

Answer to Problem 17P

The given model contains two chlorine atoms, two hydrogen atoms and one carbon atom. So, elements present in this molecular art are carbon, hydrogen and chlorine.

Explanation of Solution

The given representation of the ball and stick model shows two green spheres, two white spheres and one black sphere.

As it is known that green color represents chlorine element, white color represents the hydrogen element and black color represents carbon element, the molecular formula in the given model is CH2Cl2.

Hence, it contains two chlorine atoms, two hydrogen atoms and one carbon atom.
