Chapter 27: Problem 6

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.

Short Answer

Expert verified
The compounds with roughly the same Molecular Weight are Hexane (C6H14), Hexan-2-one (C6H12O) and 1-Hexanol (C6H14O). The order in terms of boiling point is: Hexane (69 \(^{\circ}\)C) < Hexan-2-one (128 \(^{\circ}\)C) < 1-Hexanol (156 \(^{\circ}\)C).

Step by step solution

01

Select Appropriate Compounds

Identify a alkane, a ketone, and an alcohol that each have roughly the same molecular weight (MW). This might take a bit of trial and error, but for example, you could choose Hexane (C6H14) as your alkane, Hexan-2-one (C6H12O) as your ketone, and 1-Hexanol (C6H14O) as your alcohol. Each of these compounds has a MW close to 100 g/mole (specifically, 86.18, 100.16, and 102.18 g/mole, respectively).
02

Identify Boiling Points

Next, identify the boiling points of each compound. The boiling point of hexane is approximately 69 \(^{\circ}\)C. The boiling point of hexan-2-one is approximately 128 \(^{\circ}\)C. The boiling point of 1-hexanol is approximately 156 \(^{\circ}\)C. You should try to search these up in a chemistry book or trusted online resource.
03

Rank Compounds by Boiling Point

Finally, put the three compounds in order of their boiling points. The one with the lowest boiling point comes first and the one with the highest comes last. In this case, the order is: Hexane < Hexan-2-one < 1-Hexanol.

Most popular questions from this chapter

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?

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

Rank these intermolecular forces in terms of their typical relative strengths: hydrogen bonding; dipole-dipole; induced dipole-induced dipole.

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

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.
