What is hydrophobic substances?
fats, oils, lipids are all hydrophobic.
Which of these molecules is polar?
Which of these molecules is polar
Is normal saline polar?
Yes, normal saline (0.9% NaCl solution) is a polar substance because it is composed of water molecules and ions (Na+ and Cl-) that have uneven distribution of charge across their structure, making them polar molecules overall.
What do dipole dipole forces do?
Hold polar molecules together
How do polar and non-polar bonds interact with each other?
Polar molecules reacts with polar molecules and non-polar molecules react with non-polar molecules.
In fact polar molecules are unable to go across unless?
In fact, polar molecules can pass through cell membranes with the help of specific transport proteins that facilitate their movement. These transport proteins act as channels or carriers to allow polar molecules to cross the hydrophobic membrane. Therefore, polar molecules can indeed pass through cell membranes under certain conditions.
Why is a lipid bilayer incellmembrane considered as a barrier to the diffusion of polar molecules?
Polar molecules are hydrophilic in nature. They tend to repel from the lipid content and would easily adhere or mix with the water molecules. A lipid bi-layer consists of lipids and so it would not allow the polar molecules to pass through.
Gasoline is not solubal in water because gasoline is?
Gasoline is hydrophobic because the molecules are non-polar. Only polar molecules are soluble in water.
What is hydrophobic substances?
fats, oils, lipids are all hydrophobic.
How do large polar molecules pass through the membrane?
Large polar molecules pass through the membrane by using specific transport proteins that facilitate their movement across the lipid bilayer.

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 are fat soluble molecules the only molecules that permeate across a cell membrane?
Because small non polar molecules are the ones able to cross due to the fact that the membrane consists of a phospholipid bilayer where the middle is composed on non polar tails
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.
