Propriedades físicas dos compostos orgânicos: solubilidade e temperatura de fusão e ebulição

Hi everyone, in this video I talk about the physical properties of organic compounds: solubility and melting and boiling points. In the video, I explain that solubility depends on the polarity of the compound, the length of the carbon chain, and the type of intermolecular interaction between the compounds. The melting and boiling points depend on the length of the carbon chain, the intermolecular force, and the contact surface. I solve two exercises. I hope you enjoy the video!!
