Chapter 27: Problem 14

In the ketones: a) what type(s) of intermolecular force is (are) present? b) what is the strongest intermolecular force present?

Short Answer

Expert verified
a) The types of intermolecular forces present in ketones include London Dispersion Forces, Dipole-Dipole interactions, and Dipole-Induced Dipole interactions. b) The strongest intermolecular force in ketones is the Dipole-Dipole interaction.

Step by step solution

01

Identify the Intermolecular Forces in Ketones

Ketones, such as acetone (C3H6O), are polar molecules. The carbon-oxygen bond in a carbonyl group (C=O) causes a separation of charge, because oxygen is more electronegative than carbon, thereby attracting more electron density towards itself. This results in a dipole. Therefore, the types of intermolecular forces present in ketones are London Dispersion Forces (LDF), Dipole-Dipole interactions and Dipole-Induced Dipole interactions.
02

Determine the Strongest Intermolecular Force

Among the various types of intermolecular forces in ketones, the strongest intermolecular force is the Dipole-Dipole interaction. This is because ketones form polar molecules due to the presence of the carbonyl group. These polar molecules align in such a way that the partial positive and partial negative ends are in close proximity, allowing for a strong attractive Dipole-Dipole interaction.

In the alkanes: a) what type(s) of intermolecular force is (are) present? b) what is the strongest intermolecular force present?

What is the difference between intramolecular bonds and intermolecular forces?

In terms of intermolecular forces, why does the boiling point of a particular type of compound (for example, an alkane) increase as the molecular weight increases?

Find an alkane, a ketone, and an alcohol with roughly the same MW (within 5 \(\mathrm{g} /\) mole). Rank these compounds in terms of relative boiling points.

On average, are the intermolecular forces stronger in \(\mathrm{H}_{2} \mathrm{O}(\boldsymbol{\ell})\) or in \(\mathrm{H}_{2} \mathrm{O}(\mathrm{g})\) ? Explain.
