Question

three compounds have the same types of intermolecular forces. which compound will have the largest change in temperature during evaporation for 30 seconds at room temperature? ch₃ch₃ ch₄ ch₃ch₂ch₃ ch₃ch₂ch₂ch₂ch₃

Explanation:

All compounds are alkanes with only London dispersion forces. Smaller molecules have weaker intermolecular forces, so they evaporate faster. Faster evaporation leads to more heat loss, causing a larger temperature change. Methane ($\text{CH}_4$) is the smallest molecule here.

Answer:

CH₄
