Non-polar molecules do not dissolve in water as they cannot form hydrogen bonds, and so they are hydrophobic.
A non-polar molecule is one that the electrons are distributed more symmetrically. They do not have an abundance of charges at the opposite sides, and the charges cancel out each other.

What does hydrophilic mean and how do you determine if a molecule is hydrophilic or hydrophobic?
Hydrophilic, or 'water loving' refers to molecules that are easily miscible in water. Polar molecules and ionic compounds are generally hydrophilic, and non-polar molecules are generally hydrophobic.See the Related Questions to the left for more information about how to determine if a molecule is non-polar, polar, or ionic.
What are properties of hydrophobic and hydrophilic?
Hydrophobic substances repel water and do not mix well with it due to their non-polar nature, while hydrophilic substances attract and bond with water molecules due to their polar nature. Hydrophobic substances tend to be nonpolar and often include oils and fats, while hydrophilic substances tend to be polar and include salts and sugars.
What has a polar head and non polar tail in a cell?
The phospholipid bilayer, otherwise known as the cell membrane contains many structures such as these. The individual units you speak of are called phopholipids, and are usually desribed as having a hydrophilic (polar) head group and a hydrophobic (non-polar) tail group. Hope this helps
Are triglycerides amphiphilic?
No. Because the polar hydroxyls of glycerol and the polar carboxylates of the fatty acids are bound in ester linkages, triglycerides are nonpolar, hydrophobic molecules, that are essentially insoluble in water.
Why does the tail of the phospholipid molecule of the cell membrane has a hydrophilic head and a hydrophobic tail?
tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.tail is hydrophobic because it has no charges which means it is non-polar.

Is propanol hydrophillic or hydrophobic?
Propanol is both hydrophilic and hydrophobic. The hydroxyl group in propanol makes it hydrophilic, allowing it to form hydrogen bonds with water. However, the non-polar hydrocarbon chain in propanol makes it hydrophobic, meaning it can interact with non-polar solvents.
Is hydrogen hydrophobic?
Alcohol is hydrophobic. This is because one part of alcohol is non polar. The other part of alcohol is hydrophilic.
What determines whether a substance is hydrophobic or hydrophilic?
The chemical structure of a substance determines whether it is hydrophobic (repels water) or hydrophilic (attracts water). Hydrophobic substances have non-polar molecules that do not interact well with water, while hydrophilic substances have polar molecules that can form bonds with water molecules.
What are properties of hydrophobic and hydrophilic?
Hydrophobic substances repel water and do not mix well with it due to their non-polar nature, while hydrophilic substances attract and bond with water molecules due to their polar nature. Hydrophobic substances tend to be nonpolar and often include oils and fats, while hydrophilic substances tend to be polar and include salts and sugars.
Are polar molecules hydrophillic?
No, non-polar molecules are hydrophobic because they cannot form hydrogen bonds. A good example of this would be a cell membrane. The fatty acids in the lipid bilayer are non-polar and hydrophobic, while the polar ends that face the outside and inside of the cell are hydrophilic.
What liquids are hydrophobic?
Anything non-polar is going to be hydrophobic, because water is polar. Most oils, grease, and hydrocarbons are non-polar, so water can't touch them. The word hydrophobic means "water-fearing" so it stays away. Polar substances would be hydrophilic in the presence of water. That word means "water-loving."
Why is the phosphate the polar part of the phosphilipid?
The phospholipid heads are hydrophillic and prefer the water while the tails are hydrophobic and are shielded from the water.
How does detergents help oil and water mix?
Do you know the phrase " Like dissolves like "? it means that polar substances dissolve other polar substances, and non-polar substances dissolve non-polar substances. Oil is non-polar, while water is a polar substance. To help oil and water mix, molecules of a detergent have two halves- the hydrophilic half and the hydrophobic half. The hydrophilic part of the molecule is polar, which dissolves water molecules. The hydrophobic part is non-polar, so it dissolves the oil molecules. So, basically, detergent can dissolve both oil and water, mixing them effectively.
Does the phospholipids contain a non polar component and a charged polar component?
Yes, they do. Phospholipids contain a hydrophilic (polar) head and a hydrophobic (nonpolar) tail. The hydrophilic (polar) head contains the phosphate groups, which account for the reason why the head is polar since each phoshpate has a net charge of -2. The tail consists of long chains of hydrocarbons, which are nonpolar/hydrophobic due to the symmetry of the chains.
What are the molecules in the plasma membrane made of?
phospholipids are the molecules that make up the plasma membrane and they are made of polar (hydrophilic) heads and 2 non-polar (hydrophobic) tails
What regions of a phospholipid are polar and non-polar?
In a phospholipid, the polar region consists of the phosphate group and any attached polar molecules, which are hydrophilic (water-attracting). In contrast, the non-polar regions are the two long hydrocarbon tails, which are hydrophobic (water-repelling). This dual nature allows phospholipids to form bilayers in cell membranes, with the hydrophilic heads facing outward towards the aqueous environment and the hydrophobic tails facing inward, away from water.
