Why is ethanol soluble in water but not in benzene?

Benzene because it can form ion-dipole interactions with water molecules, a bonding interaction much like dipole-dipole interactions but stronger. Ethanol because it can form London forces with water. Ethanol because it can form dipole-dipole interactions with water molecules.

What makes something soluble in benzene?

Benzene is nonpolar and water is highly polar. The only attractive forces among the benzene and water molecules are London forces. Thus, a few benzene molecules will enter the water layer, but the strong hydrogen bonds among the water molecules keeps most of the benzene molecules out.

What would be most soluble in benzene?

nonpolar solvent
Since it is an organic solvent, we can classify benzene as a nonpolar solvent. Based on the principles of solubility, the solute with the same polarity as the solvent will be the most soluble molecule. Since benzene is a nonpolar solvent, we expect that nonpolar solute will be the most soluble molecule to benzene.

Why is ethanol very soluble?

Ethanol is soluble in water primarily because of the presence of -OH group that allows or enables it to form hydrogen bonds with water molecules. In other words, ethanol is soluble in water because it is a polar solvent.

Why does ethanol dissolve polar and nonpolar?

Ethanol is a very polar molecule due to its hydroxyl (OH) group, with the high electronegativity of oxygen allowing hydrogen bonding to take place with other molecules. Ethanol therefore attracts non-polar molecules. Thus, ethanol can dissolve both polar and non-polar substances.

Is benzene soluble in alcohol?

Ethanol is to some degree soluble in benzene. In fact, benzene is used to help to strip off small quantities of water from wet ethanol. This is called azeotropic distillation.

Why is benzene insoluble?

Benzene is a symmetrical compound and thus it has zero dipole moment and is non-polar, while water is a polar compound possessing dipole moment. When benzene is mixed with water, the molecular attraction will be more and benzene won’t be able to interfere with the water molecules. Hence, it is insoluble in water.

Which of the following compounds will be most soluble in ethanol CH 3ch 2oh )?

From the choices, only ethylene glycol (HOCH2CH2OH) exhibit hydrogen bonding. Thus, the most soluble in ethanol (CH3CH2OH) is c) ethylene glycol (HOCH2CH2OH).

Why is ethanol so polar?

Ethanol is a very polar molecule due to its hydroxyl (OH) group, with the high electronegativity of oxygen allowing hydrogen bonding to take place with other molecules. Thus, ethanol can dissolve both polar and non-polar substances.
