The following pairs have to be ranked in order of increasing boiling point. Concept Introduction: Vapor pressure is nothing but the pressure of a vapor in contact with its liquid or solid form. When a liquid and vapor are in equilibrium the pressure exerted by the vapor is called the equilibrium vapor pressure. Intermolecular force: The attractive force that withholds two molecules is called as intermolecular force. The influence of intermolecular forces depends on molar mass and the functional group present in the molecule. If intermolecular force is small the vapor pressure of the substance is high and the boiling point will be low. The boiling point of a liquid is the temperature at which its vapor pressure is equal to the external pressure.

Question

For the compound: C8H17NO2 Use the following information to come up with a plausible structure: 8 This compound has "carboxylic acid amide" and ether functional groups. The peaks at 1.2ppm are two signals that are overlapping one another. One of the two signals is a doublet that represents 6 hydrogens; the other signal is a quartet that represents 3 hydrogens.

Interpretation Introduction

Interpretation: The following pairs have to be ranked in order of increasing boiling point.

Concept Introduction: Vapor pressure is nothing but the pressure of a vapor in contact with its liquid or solid form.

When a liquid and vapor are in equilibrium the pressure exerted by the vapor is called the equilibrium vapor pressure.

Intermolecular force: The attractive force that withholds two molecules is called as intermolecular force. The influence of intermolecular forces depends on molar mass and the functional group present in the molecule.

If intermolecular force is small the vapor pressure of the substance is high and the boiling point will be low.

The boiling point of a liquid is the temperature at which its vapor pressure is equal to the external pressure.
