Chapter 12, Problem 57A

Interpretation Introduction

Interpretation:

The structure of dipole-dipole interaction between two molecules of CO needs to be determined.

Concept introduction:

Dipole-Dipole interactions occur when one positive of a polar molecule interacts with the negative of another polar molecule.

Answer to Problem 57A

The structure of dipole-dipole interactions between two molecules of CO is represented as follows:

Explanation of Solution

In carbon monoxide, there is a triple bond between Carbon and Oxygen. Oxygen is more electronegative than Carbon. So due to the more electro negativity of Oxygen, the electrons in the triple bond get pulled more towards Oxygen creating a negative charge on Oxygen and a positive charge on Carbon. Due to this electronegative Oxygen of one molecule forms a dipole-dipole bond with electropositive Carbon of another molecule.

Conclusion

The structure of dipole-dipole interactions between two molecules of CO is as follows:
