When two small molecules attract each other via a permanent dipole, what type of intermolecular force is acting?
Why are small molecular solids generally poor conductors of electricity?
Why does water (H2O) have a higher boiling point than other comparable small molecules such as H2S?
Which statement best describes the structure of a typical covalent small molecule like CO2?
Which trend explains why boiling points generally increase from CH4 to C8H18 in a homologous series of hydrocarbons?
Why do many small molecular substances (like methane, CH4) have low melting and boiling points?
Which feature explains why noble gases (He, Ne, Ar…) are all gases at room temperature?
What is the main reason simple molecular substances are often insoluble in water but soluble in organic solvents?
Which explanation correctly accounts for why iodine sublimes (goes from solid to gas) at relatively low temperature despite being a molecular solid?
Why can small polar molecules sometimes mix with nonpolar solvents when they are large enough?
Which of these explains why carbon dioxide (CO2) is a gas at room temperature?
