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.

Why does soap stick to water?
Soap molecules are opposing. While one end tends to stick to water, the opposite end repels it. Suds are caused by this action. Soap molecules surround water molecules, and the parts of the molecules that repel the water point in a direction away from the water.
Are both ends of a fatty acid polar?
no, because on end is hydrophobic while the other is hydrophillic
What makes a molecule hydrophobic?
Most carbohydrate's follow (CH2O)n as their chemical formula therefore they tend to have several hydroxyl groups (O-H bonds). Hydroxyl groups are polar and therefore interact well with water. In addition there is a carbonyl group (C=O) which is also a polarized functional group and therefore can interact with water well.* note n refers to the number of "carbon-hydrate" groups.
Which of these molecules is polar?
Which of these molecules is polar
Why do oil and water hate each other?
Water is polar while oils are non-polar. Molecules that are polar will mix with other polar molecules, and non-polar molecules will mix with other non-polar molecules. Polar and non-polar molecules will not mix.
Why does glucose diffuse through dialysis tubing into distilled water?
Glucose diffuses through dialysis tubing into the distilled water as, glucose molecules are small, it could fit through the pores of the dialysis tube. It is also because glucose is hydrophillic, (polar compound), which will dissolve in water as it is a polar compound as well.
Is OH hydrophobic or hydrophilic?
OH is hydrophilic because it contains a polar covalent bond between oxygen and hydrogen, allowing it to form hydrogen bonds with water molecules. This makes OH groups soluble in water and interact well with polar substances.
Are fats hydrophillic?
No. Hydrophillic freely associates with water, readily entering into solution, and water loving. Fats, or lipids, are hydrophobic, which are incapable of freely associating water molecules, insoluble, and water-fearing.
What do dipole dipole forces do?
Hold polar molecules together
how do you explain what polar molecules are?
Water molecules are polar molecules. Both of the bonds inside the molecule are polar bonds.
Are sugars non polar Molecules?
No, sugars are polar molecules considering that they will interact and dissolve in water (which is also a polar molecule). Polar molecules will only interact with other polar molecules and vice-versa.
Why does a cell membrane need polar and non polar parts?
The cell membrane is mostly composed of phospholipid molecules. Each of these has a polar head and a non-polar tail part. The polar bits are attracted to water (hydrophilic) , and the non-polar parts repel water (hydrophobic). In the membrane, they form a double layer - like a sandwich - the polar heads stick out, and the tails form the middle, like the filling inside the sandwich. This way, the inner and the outer surfaces of the membrane are hydrophilic, being on "good terms" with the water in the outer environment and the water in the cytoplasm. At the same time, the membrane separates these two aqueous environments from each other - exactly because there is a non-polar middle layer, that does not allow polar substances to cross to the other side.
