QUESTION:
Which of the following compounds is most likely to exist as a liquid at room temperature: ethane \(\left(\mathrm{C}_{2} \mathrm{H}_{6}\right)\), hydrazine \(\left(\mathrm{N}_{2} \mathrm{H}_{4}\right)\), fluoromethane \(\left(\mathrm{CH}_{3} \mathrm{~F}\right)\)? Explain.
ANSWER:The state of a compound at room temperature is influenced by the types of intermolecular forces between its molecules.
Step 1 of 3
Types of Intermolecular Forces: The three compounds, ethane, fluoromethane, and hydrazine, exhibit different types of intermolecular forces. Ethane has weak London dispersion forces due to its nonpolar nature. Fluoromethane has dipole-dipole interactions because of the polar C-F bond. Hydrazine has the strongest forces, which are hydrogen bonds, a type of dipole-dipole interaction.
