Leej twg yog ethanol soluble hauv dej?
Ethanol yog ib qho dej cawv uas yog soluble hauv dej Qhov no yog vim yog pawg hydroxyl (−OH) hauv ethanol uas tuaj yeem tsim cov hydrogen bonds nrog dej (H2O.) cov molecules. Hydrogen bonding txhais tau hais tias kev sib cuam tshuam ntawm dipole-dipole ntawm ob lub molecules thiab nws tuaj yeem ua intramolecular thiab intermolecular .
