The explanation for difference in the physical properties of ethylene glycol and pentane is to be stated. Concept introduction: The temperature at which the external pressure on the liquid and the vapor pressure of the liquid becomes equal is said to be the boiling point. Intermolecular forces help in determining the bulk properties such as melting point and boiling point of organic compounds. A force of attraction exerted between a hydrogen atom of one molecule which is bonded to an electronegative atom such as F, O or N and an unshared pair of another atom such as F, O or N in another molecule is said to be a hydrogen bond. To determine: An explanation for the difference in the physical properties of ethylene glycol and pentane.

Answer 1

Question

Chapter 11, Problem 80AE

Interpretation Introduction

Interpretation: The explanation for difference in the physical properties of ethylene glycol and pentane is to be stated.

Concept introduction:

The temperature at which the external pressure on the liquid and the vapor pressure of the liquid becomes equal is said to be the boiling point.

Intermolecular forces help in determining the bulk properties such as melting point and boiling point of organic compounds.

A force of attraction exerted between a hydrogen atom of one molecule which is bonded to an electronegative atom such as F, O or N and an unshared pair of another atom such as F, O or N in another molecule is said to be a hydrogen bond.

To determine: An explanation for the difference in the physical properties of ethylene glycol and pentane.
