< b="" />Pentan 1-ol, n-Butane, Pentanal, and Ethoxyethane: Increasing Boiling Points< />
Boiling point is a physical property of a substance that indicates the temperature at which the substance changes from a liquid to a gas. It is influenced by intermolecular forces, molecular weight, and molecular structure. In this question, we are given four compounds: Pentan 1-ol, n-Butane, Pentanal, and Ethoxyethane, and we need to arrange them in order of increasing boiling points.
To determine the order, we need to consider the intermolecular forces present in each compound. The stronger the intermolecular forces, the higher the boiling point. The main intermolecular forces to consider are:
1. Van der Waals Forces (London Dispersion Forces): These forces exist between all molecules and are caused by temporary fluctuations in electron distribution, resulting in temporary dipoles. These forces increase with increasing molecular weight.
2. Dipole-Dipole Interactions: These forces occur between polar molecules and are caused by the attraction between the positive end of one molecule and the negative end of another molecule.
3. Hydrogen Bonding: This is a special type of dipole-dipole interaction that occurs when a hydrogen atom is bonded to an electronegative atom (such as oxygen, nitrogen, or fluorine) and is attracted to another electronegative atom in a different molecule.
Based on the intermolecular forces present, we can arrange the compounds in order of increasing boiling points as follows:
a) n-Butane, Ethoxyethane, Pentanal, and Pentan 1-ol:
- n-Butane: n-Butane is a hydrocarbon with only London dispersion forces between its molecules. It has the lowest boiling point among the given compounds.
- Ethoxyethane: Ethoxyethane is an ether with London dispersion forces and dipole-dipole interactions between its molecules. It has a higher boiling point than n-Butane.
- Pentanal: Pentanal is an aldehyde with London dispersion forces, dipole-dipole interactions, and some hydrogen bonding between its molecules. It has a higher boiling point than ethoxyethane.
- Pentan 1-ol: Pentan 1-ol is an alcohol with London dispersion forces, dipole-dipole interactions, and stronger hydrogen bonding between its molecules. It has the highest boiling point among the given compounds.
Therefore, the correct answer is option 'A': n-Butane, Ethoxyethane, Pentanal, and Pentan 1-ol.

- Pentan 1-ol: Pentan 1-ol is an alcohol with London dispersion forces, dipole-dipole interactions, and stronger hydrogen bonding between its molecules. It has the highest boiling point among the given compounds.
Therefore, the correct answer is option 'A': n-Butane, Ethoxyethane, Pentanal, and Pentan 1-ol.
