Chapter 15, Problem 15.13E

Interpretation Introduction

(a)

Interpretation:

The compound that boils at $57°\text{C}$ and the compound that boils at $141°\text{C}$ are to be identified among propanoic acid and methyl acetate.

Concept introduction:

Boiling point is defined as the temperature at which a substance changes its liquid state to gaseous state. The boiling points of organic compounds depend on their structure. The boiling point of organic compounds predicted on the basis of dipole moment, the strength of hydrogen bonding, number of carbon, molecular weight, and branching.

Interpretation Introduction

(b)

Interpretation:

The compound amoung propanoic acid and methyl acetate which is more soluble compound in water is to be predicted.

Concept introduction:

Solubility is a chemical property of substances. It describes the maximum amount of substances that can be dissolving in the solvent. The solubility of a compound depends on the nature of the compound. More polar compounds have more solubility in water due to the formation of strong intermolecular hydrogen bonding with water molecule.
